Your comment is like if someone said “You should use a Linux phone to get away from Google and Apple” and you responded with “Android uses Linux”.

I promise as someone extensively familiar with MediaWiki who even administrates an indie wiki that this comparison makes absolutely no sense, and I think you're reaching to make the OP's meme make any actual sense when it clearly doesn't. If we're reaching into Linux, this is more (still somewhat tenuously) akin to someone telling Ubuntu users that they're not using "real Linux". They lack the language to express Ubuntu's actual problems which really exist and so resort to vacuous gatekeeping instead.

Edit: Actually, the analogy doesn't even get base enough to describe that. It's like a meme where Geordi rejects the Ubuntu logo and accepts the Tux logo, and then under that is the OP trying to argue that Ubuntu isn't a "genuine" operating system.

"Touch some grass", if anyone else is unfamiliar with the tla. Rather rude, since that is not even slightly clear in the original meme and I appreciated the extra information...

That, however, does not weaken my point at all.

It invalidates your point. You're trying to gatekeep what does and does not constitute a "wiki" while clearly having no idea what that word means. And if you knew Fandom uses MediaWiki, it clearly doesn't show in your meme, because a) Fandom is powered by MediaWiki so it's not mutually exclusive like Geordi implies, and b) like Fandom, most indie wikis in my experience don't use the "Powered by MediaWiki" icon either (just in case you'd go with that bizarre, last-ditch non sequitur of an argument). Your meme is nonsense if Fandom uses MediaWiki, which it does.

As for "genuine wiki", Fandom clearly meets all the points for being one – let alone that it literally uses the de facto wiki software. I'll let Wikipedia speak for this as an expert witness:

A wiki is a form of hypertext publication ✅ on the internet ✅ which is collaboratively edited ✅ and managed by its audience ✅ directly through a web browser. ✅ A typical wiki contains multiple pages ✅ that can either be edited by the public ✅ or limited to use within an organization for maintaining its internal knowledge base. Wikis are powered by wiki software, ✅ also known as wiki engines. Being a form of content management system, these differ from other web-based systems such as blog software or static site generators in that the content is created without any defined owner or leader. ✅ Wikis have little inherent structure, ✅ allowing one to emerge according to the needs of the users. ✅ Wiki engines usually allow content to be written using a lightweight markup language ✅ and sometimes edited with the help of a rich-text editor. ✅

It doesn't seem like you're "well aware" of anything you're talking about except the general (correct) sentiment that Fandom sucks. Fandom sucks for so many reasons that it's legitimately impressive you managed to miss all of them while making this meme. I was being earnestly polite when you told me to touch grass, so since even that is apparently escalatory, I'll just... not.
