I think Github is a relatively simple issue. There isn’t really a shortage of european (or just selfhostable) alternatives, and the way git works means that most contributors have complete local copies of the codebase. TBH I worry more about the ability of american contributors to continue working on a project if the code is hosted in europe - basically a lot of open source developer teams could end up being split or shut down entirely. And the bigger projects like Linux and a lot of the intermediate layers between the Linux kernel and applications are majorly backed and developed by american companies and their employees.
Yeah. Someone has to put in the work for packaging an application if you want it as a .deb/.rpm etc. package and deal with any bugs that might come up, and it’s not going to be me (speaking as a user, not a developer).
That said, I also painted myself into a corner when it comes to harddrive space. LUKS can be complicated, man …
