I love it but the main power a union wields is the collective action of the members to strike.
When the union says "Ok, Apple isn't cooperating, so everyone... " ...actually, what would you have the members do? Turn off icloud? Stop buying new airpods? You will never get all the "users union" members to give up one atom of convenience.
If the union members are willing to strike, i.e. go without pay for an arbitrarily long period of time, why wouldn't users be temporarily willing to go without anything, when they know there is a good self-interested reason for doing so?
Saying "people won't do that" is just a self-fulfilling prophecy. Convince them that it's in their interest and they will.
