Not so sure. While they may be doing more than FB obviously, both example parties you listed are more than happy to support privacy invasion when it furthers their ends. You don't need to lower your standards to find counter examples nor do you need praise those that are only a little less bad. In my view the word "all" in your statement is verifiably false. We should be more nuanced and call out bad when we see it no matter the org instead of giving out org-level labels.
Android phones are also effectively proprietary (especially phones from manufacturers such as Samsung and Xiaomi) and seemingly get slower over time. But yes, the apps are cheaper/free thanks to sideloading and a good community.
(RMS-Mode On) What I'm referring to as Android, is in fact, Google/Android, or as I’ve recently taken to calling it, Google plus Android. Android is not (really) a usable operating system unto itself (for most people), but rather another component of a fully functioning Google system made useful by the Google Apps, Google Play Services and vital system components comprising a full OS as defined by the end user.

If either way you're going to have a proprietary phone, you might as well pick the one that has less of an interest in data mining you.
Why the scare quotes?
At least some are trying to counter all this privacy invasion (EU, Apple, etc.) Let's hope they will continue doing so.
