What would you have them deface?

Hi Tina
you should be able to block that specific string if you don't want to see them
How does one do that?
From you. It was your money but then after you give it to them, it's their money.
the compatibility lists
What compatibility lists? That's what OP is asking for.
No, it does not mean any of the projects you mentioned will be unavailable. None of those projects are free software OSes.
FOSS ROMs
What do you mean?
the firmware of the CPU
AFAIK, there aren't any mobile CPUs with microcode like Intel CPUs.
and associated hardware
Rockchip RK3399 is the best you can get from my understanding. The newer Rockchip RK3588 requires a non-free blob for the GPU unfortunately.
What other climate activist groups?
