As much as I'd like to believe that I'm worthy, I'm not.
This stuff isn't easy and I'm more than happy letting someone else do it at the expense of some downtime.
No, I don't want to be in the business of running my own Github clone. That's what I pay Github for.
Why do you pay salary to employees to buy food when you can just run a farm next to the office and save money by operating the farm and giving the employees food directly? You'd save money by not having to pay as high of salaries, and farms don't even need 24/7 devops teams.
Eh, if you want to be able to continue working, deploy and what not as normal during weekdays, I'd suggest also moving to Forgejo Actions if you're moving anyways. Not 100% compatible, but more or less the same, and even paying the same but with dedicated hardware you'd get way faster runners.
For OSS, the unlimited free minutes of multiplatform CI offered by GitHub are literally impossible to replace. Maintaining runners yourself to do the same things would be somewhere between a part- and full-time job.
Yeah, how you think the ecosystem got by before GitHub even had actions? Y'all don't remember Travis CI et al anymore?
There are more CI services than what Microsoft offers the world, sometimes it's worth looking around a bit.
"Codeberg is a non-profit, community-led effort that provides services to free and open-source projects, such as Git hosting (using Forgejo), Pages, CI/CD and a Weblate instance."
Never say impossible.
Github is still "new" to a lot of us. OSS existed well before it, and will continue to exist well after.
And yes, if we make OSS just about hosting the code, things are much simpler. If you're a piece of desktop software though, and you have users, they'll typically (and reasonably) want auditable signed binaries on all the platforms you support, which requires multiplatform CI.
