The point of guerilla style social media activism that exposes oppression, is to reach as many eyes as possible.
Are there alternatives? Sure. But do they reach anywhere near the same size of an audience? Unless I’m extremely out of touch (I do not consume that kind of social media directly), then it’s not even remotely close.
Maybe BlueSky is bigger than I think it is, but I rarely ever hear about it outside of very niche circles (like lemmy).
My point stands. Despite all the mishandling of Xitter, it’s still a powerful tool to get grassroots news out for things like protests, oppression. The platform is certainly worse than it was before Musk, but it’s still a decent tool for this specific usecase.
