I think it can be read as a PSA rather than a boycott call to action. Fandom is so horribly thrash that people are doing a disservice to themselves by using it, specially since now most big wikis there are going to just be vandalised graveyards since the original teams left for bigger projects.

If you’re searching for something related to a game, fandom is usually the first thing that pops up due to SEO, but you’re not losing on some cheaper or higher quality product like you would if you chose to instead use some alternative. The title is a bit of clickbait (and the author is probably a lib) but the message isn’t really the usual “this company has an unethical supply chain” and more like “this company produces useless trash.”
