Sullivan is more or less arguing the FSF party line, that both Apple and Adobe are unethical because both are promoting things that aren’t free-as-in-freedom. That’s great. So what mobile phone should an FSF devotee buy? Good luck with that.
Probably none. That’s one of the consequences of sticking by your principles. Sometimes you have to not do things that go against your principles. I admire the FSF guys for actually doing that.
