I personally think UK-based folks have a personal duty to defy the OSA.

No idea how that'd go but uh... OSA is a load of horseshit and you should do the right thing by not obeying a single thing required by it.

I am not a lawyer. But this is your time to act (or not act at all by not lifting a finger to react to its demands).
Folks all talking about protesting and rioting etc and then give in to the simplest things.

There's no way they can reach so many small-potatoes operations. Fuck 'em.
