SUSE has its line of business in servers and cloud computing. Opensuse has desktop users as its main asset. Not wanting the company’s name to appear on the distribution is because the typical users of the two are increasingly different, as well as suspecting that Leap will not continue as SLE’s 1:1 solution. Suse’s decision not to have its name on the distribution means that it will be increasingly distanced from the community distribution, which is primarily run by Suse employees, so it is the company’s decisions that will shape the future of the distribution.
A company’s decisions are based on the benefits of its line of business, not on the benefits of the community outside its customers. This is a statement of intent that in my opinion breaks the relationship of trust between company-community. It is time to look for another distribution, the chameleon has focused on its profits rather than on the benefits for the community.
