Cirrus gave a ton of support for years to open source projects. I congratulate them on cashing out. Running a business like Cirrus did is always a hard road and I will never fault folks who gave time and resources on their platform away for taking the money.
I wish Fedor and everyone at Cirrus the best of luck and OpenAI and thank them immensely for the years of free CI they gave to us in the Pony programming language despite it not having any marketing value to them.
