The best argument I heard to defederate and have noting to do with Meta is this; this is the company that had/has a platform where hate, disinformation and lies have created a divide in society, several older generations were ‘socially engineered’ to start to think differently, more absolute and right wing. In short, Meta has a platform known for causing division amongst countrymen and families.
Pre-emptive nuking is what is needed, followed by some DDT thrown over it for good measure. This needs to stop. This is not a technical decision, this is a social one in order to try and save us from that shitshow FB/Zuck/Meta gave us.
