Gab were just a bunch of reactionary amateur retards, who were easily scared shitless by “demon tranny hackers from hell” and a few FSE trolls.
Meta on the other hand is a constantly metastasising cancer filled with more cancer that gives you AIDS, backed up by a huge army of corporate lawyers and a gang of paid-off journos and politicians. They will just take over of what they want, threatening everyone in their path with patent and copyright infringement lawsuits and running smear campaigns to destroy people’s reputations. Good fucking luck fighting that!
