@angdraug Thanks for your reply. I am already donating and supporting projects, especially in the realm of #LinuxAudio.
Regarding the dependency graph in the organization I'm still trying to convince my university switching to a #BigBlueButton or #OpenTalk provider instead to keep on making us #Zoombies.
Unfortunately, this may become a rather legal than technical argument. However, if it doesn't even matter in the end, my complaint might be at least a statement and could encourage others to fight for #DigitalSovereignty in academia.
