How is this question not moving the goal posts? The top comment claims that Apple Silicon is more locked down than previous Mac iterations. It is not. Does that say anything about future hardware? No. But we are in the same boat with the raspberry pi. If broadcom decides to fuck over hackers who want to use alternative is software for newer hardware iterations, they can.

Anything can happen in the future. When purchasing hardware, look at what you can do with the device that is in front of you.
