SUSE also has multiple controversial pacts with Microsoft, and has for a long time. Such as the Novell-Microsoft agreement.
There was a time when it looked possible that MS was going to sue lots of Linux projects, and SUSE immediately jumped into a cosy relationship with MS so that if it did happen, they’d be shielded. This was interpreted as a fuck you to other FOSS projects by much of the community. (Was a long time ago though)
