Why do politicos hate it?
Easy.
As far as the ruling class is concerned, we peons are all criminals. They want to block off all ways we could get together and decide to do something to remind them what the term "public servant" actually means. If they can sniff out all talk of organising against the ruling class then all they need to do is lock up the instigators and carry on fleecing the public purse to feather their nests undisturbed.
