As much as I hate Meta, it feels like the lesser of two evils. Elon has already brainwashed tesla fanbois and is likely going to use Twitter to further his own agenda political or monetary. He has already silenced critics there.
Meta is in the crosshairs of regulators after Cambridge Analytica.
Twitter is dead anyway, account walling tweets, decreased moderation and rate limits. It's all worse for any advertiser who has stuck with them post-Elon
