Doesn't surprise me. Musk has cultivated and emboldened racists, homophobes, cryptobros, misogynists, and the far right and the platform has turned into a cesspit. Meanwhile scammers & bots run rampant and the blueticks stink up every thread with cretinous remarks and trolling.
I wouldn't be surprised if a lot of people have just given up with it, or moved to another social media that isn't so toxic.
