As a software maintainer/distributor, I don’t think we at Red Hat are the ones responsible to publish data sheets. That’s the job of the hardware manufacturer/vendor. When they decide to only offer it in non-public ways but allow us to help with getting the drivers upstream AND open source, it is a deal you might not like, but I, as a pragmatist can accept. We’re not the only Linux distributor working this way. Ubuntu/Canonical and SUSE don’t work that different from us on this. Again. You may not like it, and I understand that, but it has lead to making Linux a first class OS on Lenovo with an upstream first goal. I like it that way, even if it can become even better and more open.
