This is something I and other tabletop bloggers like thydungeongal have said repeatedly in the past, but I think it bears repeating.
If you don't like WotC due to the recent scandals they've been involved in (such as the OGL thing and sending the Pinkertons to someone's house) and you are serious about disrupting the economic and cultural stranglehold they have over the entire tabletop hobby, pirating D&D products is infinitely less important than exploring, discussing and platforming games and creators outside of the D&D 5e ecosystem.
A person who pirates every single D&D product but continues to exclusively play, discuss, talk, and blog about Dungeons and Dragons Fifth Edition is not doing as much as someone who religiously pays for every D&D product but also gives some of their precious time and attention to games that aren't D&D, especially if they have any sort of platform or audience.
Over the past few years, as people have observed how 5e is pulled between different groups of people who want entirely different things, a lot of folks have suggested that WotC should split the game into different versions, bring back the basic/expert split, etc. And while that would improve the game considerably, they won't do that for one simple reason: their market dominance is entirely based on people treating D&D as the only choice.
D&D is a crunchy, combat-centric game built for dungeon crawling that is primarily played by people who don't want any of that. If they were choosing a game, they would choose something else. So the 5e social ecosystem is built to create the illusion that 5e can do anything, that it's an easy game --the easiest game!-- and learning anything else would be too difficult, and other games are for gatekeeping nerds.
But that illusion is really fragile. Reading a single other game is often enough to shatter it. Playing something else, something that actually suits the gameplay you're going for or brings new and exciting ideas to the table, can change someone's view of TTRPGs forever.
If you're skittish about other games, there's plenty of great games that make their rules available for free. There's no commitment lower than downloading a free pdf to look over some time. And you could end up discovering something amazing, something you'll love! Even if you don't, the mere act of considering another option is enough to start eroding the grip Hasbro has on the industry that makes all their bullshit practices possible.
