Conversely, Pine64 hardware seems to have a pretty dedicated developer community among the various mobile Linux distros, and considering the significantly improved specs of the Pinephone Pro over the original model, I'm wondering how many people will opt for the even-more-expensive Librem 5 in the future after the Pro has been out for a bit and some of the early-adopter kinks have been worked out, considering the issues Purism has had seemed to have with reliably getting inventory out.

Heh, with how the developers cooperate, you would never know there was competition.
But seriously, if you do want to fund Mobile Linux, buy a Librem 5. Purism funds dedicated GNOME/Phosh/etc. devs to work on making Mobile Linux a polish experience, and many of them also help to make sure it works on the Pinephone/Pinephone Pro. Heck, sometimes I think many of their employees spend more time helping out Mobian users on a Pinephone than they do Librem 5 users.
As much as I like Pine64 (I think making a $150 Linux Phone was an amazing idea!), they exclusively only fund the hardware development. Drew Devault has, IMO, a good overview of criticisms of Pine64: https://drewdevault.com/2022/01/18/Pine64s-weird-priorities....
I own both the PinePhone and Librem 5 USA, and I'm seriously impressed by the amount of work the Purism devs do for PinePhone users (who are the majority of the Phosh users).
