@aud @x4nw @nkizz @stylus Fun story:
GitHub Enterprise Server (the on-prem version of GitHub) was originally based on Ubuntu. At some point shortly after I joined the company, I helped lead a panic migration over to Debian, because word on the street was that Canonical was going around and hitting people that were selling VM images based on Ubuntu up for a percentage of their sales. Their basis for this demand was "use of their trademark" - ever notice how they shove the text ubuntu into the version number of every package in their distro? Yeah. That.
Anyway, on my way out, post Microsoft buyout, I was forced to participate in a migration from Debian back from Ubuntu, because Ubuntu had been sprinkled with whatever magic pixie piss the US military likes its software to smell like, and Debian had not. I brought up the original reason for migrating to Debian, and asked if our lawyers had cleared going back to Ubuntu and/or if Microsoft had some relationship with Canonical that allowed for this. I got told off hard for questioning a Microsoft manager, and especially for daring to even inquire as to the relationship between Microsoft and Canonical, and was informed that it was absolutely not my place ever mention any possible legal issue with any decision ever.
