I like the idea of their products, but I just wish Unihertz wasn't so sketchy -- they refuse to release any kernel sources. (Which is in direct violation of the GPL!)
I generally remember that there's some problematic issue with Unihertz but often seem to manage to forget exactly which issue it is.
Non-compliance with the GPL is frustratingly common (over a huge range of company sizes too).
Not at helped by the fact that the community managed to (stupidly) burn bridges with the one person who seemed to be effecting actual change within Chinese companies with regard to GPL compliance.
