"It's our responsibility to choose and support products that respect our rights and empower us. Vote with your feet."

I think you mean 'wallet'.

But it's hard for consumers when as individuals they have little choice.

Mobile OSs come in 2 flavours. Wherein there is lack of competition, it's nary impossible for consumers to 'vote with their wallets' because there's few other places they can go.

I think this might call for some intelligent regulation.
