You don't think that commercial products can't get good (or bad) coverage in a place like this? In any discussion of hardware, software (including, for example, video games), cars, books, movies, television, etc., there's plenty of profit motive behind getting people interested in things.
There are already popular and unpopular things here. Some of those things are pretty far removed from a direct profit motive (Linux, Star Trek memes, beans). But some are directly related to commercial products being sold now (current video games and the hardware to run them, specific types of devices from routers to CPUs to televisions to bicycles or even cars and trucks, movies, books, etc.).
Not to mention the political motivations to influence on politics, economics, foreign affairs, etc. There's lots of money behind trying to convince people of things.
As soon as a thread pops up in a search engine it's fair game for the bots to find it, and for that platform to be targeted by humans who unleash bots onto that platform. Lemmy/Mastodon aren't too obscure to notice.
I actually got auto-added to some bullshit sub that was "for people with so much karma." I don't remember what the number was, because it was such a useless sub that no one engaged with.
