I've been running self hosted runners for my company using Actions Runner Controller (ARC) on my own kubernetes infrastructure. Could never really get the devs invested in GitOps style dev cycles so I may just chuck actions and use a more nightly or on demand style build server since that seems to be what they desire and expect. I always expected this day to come so my actions use very little github/actions specific stuff, mainly they just kick off scripts already. I do wonder how hard it would be to create my own github API pollers etc but not sure I want to invest any further in anything github specific. Good news is the effective date is March and the initial prices for my usage will probably be very low but I fully expect them to push further price increases / monetization / lock-in.
