yeah, you never know what's going on behind the scenes on web2 and beside anything you mentioned, there hardly any privacy there... i mean in UK they are arresting people for opinions expressed on facebook, here no one can come and catch you, there is not authority sending your data to police and such

also on web2 people trash talk and then delete or just say "my account was hacked!", here it all on chain, you can't delete and being hacked is harder but you will lose your account forever if it happens not just "temporary"
