Raise money and awareness through non-destructive means, start a program, work on the problem yourselves and hope more people join in. Start a fucking tik-tok challenge, I don’t know, honestly.
But throwing soup at art is just cringey and makes you look weird. No one is going to be on board with that but other soup-throwers. Then you just have a whole group of people travelling around throwing soup at monuments and nobody knows what the fuck your point is, as evidenced by this comment section.
It’s hard to not sound snarky here, but you could play another system that’s not seen as a commodity to be passed around Corps for profit.
I switched a couple years back, and honestly couldn’t see going back even before their licensing drama. As a GM, their books are so hard to make work, and expensive for what you get. D&D became too much of a product, and the game has suffered. 3rd party stuff has always had better value and usability compared to WotC books (few exceptions), and other systems give much better support for GM’s to actually run the game.
The coolest shit you do in D&D is the stuff you’re group comes up with at the table, and you get that with any system. Tencent also can’t buy that, so there’s nothing stopping you just playing 5th Edition, and not 6th (or One, whatever Marketing ends up calling it).
