@anotheruniqueid@techhub.social @mikegalsworthy twitter is/was so bad at data security/privacy that the federal government had to step in and slap them around to the tune of.. 5 billion, I believe?

I agree that mastadon servers in general are more vulnerable. There will be multiple attacks, supply chain, protocol exploits, etc that cut the network to ribbons if the overall userbase grows enough to warrant the attention. If you've got a password unique to mastadon though, you don't have much to worry about except someone impersonating you - nobody's collecting ridiculously invasive details about your interests/activities here
