Once upon a time, there was a wiki farm called Wikicities. It attracted wikis far and wide because it had so many cool features, and did not involve as large a hosting expen$e as would self-hosting. One of those features was the capability to customize a wiki reader's experience. Wikicities grew and prospered, attracting one wiki after another, until it was full of wikis. Then, one day, they decided to add marketing and advertising to the mix (see also slippery slope). They held focus groups to figure out the target market so they could get the advertisers to help with the large cost of maintaining a wiki farm.
They decided to rebrand themselves Wikia. They justified adding the adverti$ing to various wikis by the agreement that the wikis (especially those already in existence at the time of rebranding) and their readers would have options to view the wikis in the skin of their choice. One was their Monaco $kin, another was the traditional wiki look that resembled Wikipedia. The Monaco had a pretty little background, and was $hiny and flashy, so they were certain people would choose to view the Monaco skin - and its related advertisements, often in the form of videos, rather than the traditional wiki format.
But, they were wrong. Also, some wikis were resistant to being plastered with advertisements, and/or had content that adverti$ers did not appreciate.
They tried in vain to convince these wikis to change, first by coaxing them, flattering them, and begging, then by implementing forced changes. These changes also included censorship, including content that might offend little old ladies, certain religious groups, overprotected kids who have no access to programs like "Net Nanny" and don't have anyone watching them when they go online, and the entitled moms of the world (you know, the ones who pretend to be offended just so they can get their way, and don't know how to pick their battles). Not to mention those who think their ideas are all better than everyone else's ideas (look up Dunning-Krueger syndrome).
After all, if you don't like the message, just censor it....after all, it's what the 45th President of the United states, the Puritans, and all the medieval Crusaders would do (some with swords, some with stockades, and some with an expert team of lawyer$ - see also Gag order). Just go back in time and ask Galileo. Or, go to heaven, and ask your Messiah why he thinks he was crucified (hint: it may have been due to either the marriage of religion and state, or the dent in business he made when he raided the temple). Besides, TRIGGER WARNINGs are such a trendy, millennial thing to do, and we ALL love trend$. Never mind that most wikis can be edited by literally ANYONE, and are a collaborative work between several or many editors. So, instead of working to change the wiki in the way a normal person would do, and discussing the content with other editors and admins, or even bringing their complaint to admins, they threatened to $ue instead. Or, they put in for copyright claim$. (Any business can do that.) Or, individuals complained to the advertisers and threatened boycott$ if they didn't heavy-handedly force restrictions on sites they sponsored. This, by the way, is exactly why some sites hated advertisers in the first place. Because it had always been only a matter of time.
So, some wikis left Wikia. Refusing to be "bullied", Wikia left the abandoned wikis up, so to hide how many wikis had simply abandoned their site and moved to a new one. Then vandal$ swooped in. One vandal put in a nude in ASCII characters on one of the sites. (Google "ASCII Art" if you have no idea what I am referring to by ASCII characters.) Others put curse words or porn pictures (lacking any context) all over the abandoned wikis. And since the old wiki admins had all left, nobody was left to clean up all the vandalism. So Wikia hired some anti-vandal patrolling staff to fill in for non-existent wiki volunteers.
But soon, those $taff started costing Wikia money. A lot of money. Enough money that they weren't getting enough from adverti$ers to fund the hosting for all of these wikis, abandoned or not. So they tried to force their new skin (now with VIDEO advertising!) on all the wikis. However, some $killed admins at a few sites that had programming and coding experience managed to circumvent this so although the new skin was used, the old skin was displayed. Some time later, Wikia changed the format of their wikis to force a Wikia navigation bar at the top of all their wikis, effectively forcing them to run within a frame. However, one or two wikis, with actual programming college students or experienced programmers, managed to circumvent the change of skin with this too.
So, Wikia rebranded itself again. It called itself Fandom. It focused on topics that were far more inviting to advertisers, like comic franchises that had birthed massive toy sale$ and had several movies to advertise, manga franchi$es, Youtube wikis (a great place to advertise youtube video$, which many advertisers just love), and recipe wikis (a great place to advertise food store$ and even restaurant$). Humor wikis....not so much, since standup comedians and comedy shows tend to advertise by word of mouth. And the ones that had been particularly vocal and active about not using the Wikia skins...Fandom simply closed their wikis. After all, the more articles a wiki has, the harder it is to strictly control the content, especially in a timely manner. It also cost$ more money to host a wiki the more article$ it has. They also FINALLY got rid of their abandoned wikis.
By the way, on a completely unrelated note, Nine Inch Nails "Head Like a Hole" is a song that will NEVER get old. If you don't like hard rock, the lyrics are still worth reading, and it is probably only a matter of time before someone remakes it as a rap song or an electronic club mix. If that hasn't been done already. Not that I don't like dance music. Also, if you haven't figured that out yet, I replaced the S with $ just for fun.
