One of his main complaints is "People who promote Linux, don't run Linux" and he specifically focuses on those who hold Linux-related talks at conferences on devices that don't run Linux on the desktop.

Can you look at https://www.linuxfoundation.org/membership/members/ and easily point out those companies, that have a crucial business stake on Linux on the desktop? I can't.

Most people, who are paid to work on Linux and its surrounding ecosystem, are working for companies that are interested on Linux on servers / the cloud and I don't think that it is fair to criticize them for not joining the idealistic movement of bringing Linux onto more desktops.
