I agree with your overall point, but I believe that this could (and hopefully will) change without any top-down mandate. I think we just need a minority group of people who are unbreakable in their intolerance of ad-funded services, much like RMS and the first FOSS developers were intolerant of running any type of proprietary software.
It dawned on me with the whole WhatsApp thing of fucking around with the privacy policy: I didn't mind using it before, but that was the final nail in the coffin. I uninstalled it and I told my friends/family that whoever wanted to reach me could do with Matrix, phone or plain email. I also would gladly help set an account for them on my communick group plan. Of course not all of them did, but the ones who did realized that it was not the end of the world to use a new app and were glad to be able to say that they were not enslaved to whatever Facebook had to offer. Some of these friends even signed up for their own plan, so they could invite more people on their own, etc...
