Anyone can edit Wikipedia is a false belief. There are moderators who monitor popular posts from being edited. These moderators are usually from PR management companies who spend a lot of time editing pages to appear legit and also sell their services for a fee.

So, NO, anyone cannot edit it or even add factual data without the approval of a “moderator” who may be awfully biased at not letting bad comments about their clients publicized.

The founder himself is not hiding his bias. It’s always been used as political and commercial PR by politicians and companies but with a cover of being an “Encyclopedia”. Just like how many NGOs are fronts for government intelligence agencies.

If you want to prove me wrong, go ahead and give it a try and let’s see how long that “edit” lasts.
