Batteries on Silicon MacBooks can't be replaced under warranty by third parties

I have been a MacBook Pro user since about 2002.

With the poor quality of my last two keyboards, and the inability to repair them, I have decided my next laptop will be some sort of FOSS solution based on something like a Framework Computer or System76.

I'll really miss OmniGraffle - one of the few proprietary programs whose license generally allows reverse engineering.
