If you unlike their software or hardware, then just stop buying it and buy or support free software and hardware. Freedom is not free.
That's a half-measure with limited impact. Why spend considerable resources freeing up a small number of works? The right thing to do is to abolish copyright straight up. At the very least, fix copyright by significantly reducing duration so that copyright ownership is reassigned to the public automatically at zero cost regardless of what monopolists want.
> just stop buying it
People won't have a choice. They'll either buy locked down hardware or they won't be able to consume anything. Streaming services have already started enforcing DRM rules that prevent owners of free software and hardware from consuming their content and it's illegal to circumvent this even if you pay for it.
