You're not wrong, but technical artefacts can be an important step in the right direction. I came to my bank, showed them my Librem 5 phone and asked where I can download an app for it. It was a much clearer message than "but Android isn't free!" (which is of course true). I do the same with governmental services. It also makes it much easier to explain to ordinary people that the choice must not be artificially restricted to just two megacorps.
