Recognizing a car could be safer isn't contradicted by owning one. If anything, ownership should give you more insight into the material problems of the item in question.
Likewise, society is just everything. So suggesting improvements isn't contradictory.
However, there is some hypocrisy in lambasting the maker of the very luxury goods you purchase for exploiting people. You are kind of justifying the companies' exploitation by purchasing from them. And you can advocate for change from these makers without supporting them with your money.
And some people do come with the attitude of "I don't want to change a single thing about my behaviors or sacrifice a single thing, but I expect the world to get better somehow."
And if you point out any hypocrisy in a person’s action, someone will trot this out as if we can never call out people for contributing to a problem they are complaining about even if contributing is completely optional.
No matter which phone is chosen you can call someone a hypocrite for thinking that both google and apple ceos are overpaid. The illusion of a free market is no defence.
