Are there any e-ink readers with a physical keyboard and navigation buttons like a kindle 3 that aren’t amazon made? And ideally ones that are somewhat hackable and not centrally controlled by an evil megacorp?

I had a kindle 3 a long time ago and would like something that is similarly laid out but ideally not evil
