Sounds like either Pine64 has grown past this and decided to pivot, or has been losing revenue due to a lack of customers from this niche market. Personally, as a hacker I love playing with different OSes. However, if I was to use any open source device like a PinePhone or Pine64 board to build something, I'd prefer a stable environment backed by an established foundation. Environment setup is hell, and figuring out which open-source OS works best, if it will be supported in the future, and how to install it would slow me down immensely.
