All hardware is open if you're willing to open it up ;)
But reverse engineering isn't as easy as my snarky response implies. But I do think more of us should get into hardware hacking. It's the only way we have to fight back. I'm tired of this "own nothing" paradigm and being forced into whatever dumb thing they want is to do. And it's so dumb too. There's not many power users but there's a disproportionate amount of resources dedicated to fucking us over
It's a shame open source hardware isn't a thing in this area, but we've been here before. (Buying locked down devices and installing alt OSes.)
