Long story short they burnt good will buy pre selling Linux phones with a “no questions asked” refund policy. The phone was delayed for literal years and they changed the refund policy such that you couldn’t really get a refund. People were rightfully upset.

IBM/Redhat do the lion share of Linux development.

I think it’s a worth while effort. I know they burnt a lot of good will in the past but they are a major contributor to the Linux mobile effort. We shouldn’t rely on IBM for everything.
