Unless some major customers are moving away, I don't think they are going to seriously care about it.
What is the quality-first, high uptime alternative to GitHub? My employer uses both GitHub and GitLab, and while I think GitLab is better, its quality also frankly sucks. It's riddled with bugs that have just been marinating on the issue tracker for years, and the most common "fix" for gnarly bugs in the CI platform is "revise the documentation to reflect the existing (broken) behavior".
I suspect some companies may already be considering it. Especially with the wealth of alternatives today.
