Uh, if what your saying is true, that sounds like an absolute victory for Spez. He never wanted good communities, he wanted communities he could market to. Having the idiot right wing that buys Chinese hats that says MAGA is absolutely the audience he wants.
In fact, if you're all correct and the old social media is just straight going to the right wing and the left wing goes underground to techie sites like Lemmy, their voices will get magnified. Which is already happening with bud and Starbucks. Oh we are fucked...
