I really hope Purism's Librem5 pans out for this very reason. A third alternative. I don't want Windows Phone, since that would not buy me much more privacy than Android with today's Microsoft, so having an open 3rd party mobile platform would be the solution here, I think.
I agree it is an exciting phone, but what are the privacy gains versus an android phone with lineageOS and f-droid foss apps? AFAIK it's just the baseband code. Convincing regular users that opensourcing the baseband will solve any problems seems pretty DOA when you have the very visible google play services tracking issue and no on cares.
Nevertheless, I hope that Purism will be able to deliver a product which is as easy to use as a "normal" Android device with those privacy/sustainability features as a bonus. That way I might be able to give the people who ask me which phone they should buy next some good advice.
