I think a concern for the business is whether other people can help maintain the system. As such don’t go too custom and roll your own. Take things like nextcloud and see if you can fit the requirements by bolting on a few docker services. Keep it simple by using “appliances” where it makes sense (dedicated NAS?).

Who needs IP laws when you have EULAs that bar competition? Certainly not corporations with their armies of lawyers.

Eztv is good enough for me anyways

GitHub definitely would and has in the past. YouTube-dl is on GitHub and gets a pass because it is used by researchers and archivists, both are fair use. forgejo.org would let you be your own fedi-github and might be worth checking out (could be easier than designing a plugin system and additional repos).
