I'm with you there. Got an 8 Pro 2nd hand for this and sold on my iPhone 2nd hand as well. Graphene is looking into supplying their owm hardware, hope they make progress while so many consider the switch.

I'm planing to do the same with my MacBook Air, got an M1 version that I will swap for the last Intel version. I can put Linux properly (Asahi for M1/2 is incredible but still limited) and the other person won't give new money to Apple for their upgrade.
