Drastically nerfed the quotas. FOSS projects with a valid license used to have GitLab Premium access to shared runners and now even FOSS projects with a valid license get a rather useless 400 minutes. They also require new accounts to add CC info just to use that paltry sum which means FOSS projects can't rely on CI passing on forks to ensure a merge request passes the checks before merging, as even if you have project specific runners set up forks don't use them and neither to MRs.
I wish companies didn't offer what they can't support from the beginning rather than this embrace, extend, extinguish shit. I guess in GitLab's case there was no extend, it was just embrace FOSS projects and let them set up CI pipelines and get projects depending on the shared CI runners as part of merge request workflow for a few years and then extinguish by yoinking that access away and fucking over everyone's workflow, leaving us scrambling to set up project side runners and ruining checks on MRs.
