Github for open source was always my favourite part of it.
Github for private repos has long had security issues, every time a serious issue announced it makes me wonder how long it's quietly existed and been exploited, and how many other holes are currently exploited that aren't well known.
Before github, people hosted their own repos all the time. Learning about alternatives, even if they aren't for you in all cases, is still worth it.
Has anyone had any issues with codeberg or other alternatives?
