TBH the open source nature of gitlab means that any sufficiently large and clued-in hosting company (think: servercentral/deft/summit, whatever it's calling itself these days, or one of its competitors) could put up gitlab instances for people to use and meet more nines of uptime than github. It doesn't have to be the gitlab company itself running servers with the httpd and back-end database.
I understand the meaning, however, in that they're well positioned by having the company name and domain name, same general way that non-technical people will pay wordpress.com to host their blog/small website because it's very easy, rather than DIYing it or paying a 3rd party.
GitLab isn't open-source. It's "open-core". Third parties hosting GitLab instances don't have access to the same range of features that GitLab-the-company does.
Yes, copy and pasting from the gitlab site:
"Editions There are three editions of GitLab:
GitLab Community Edition (CE) is available freely under the MIT Expat license. GitLab Enterprise Edition (EE) includes extra features that are more useful for organizations with more than 100 users. To use EE and get official support please become a subscriber. JiHu Edition (JH) tailored specifically for the Chinese market."
Personal opinion, but I think a great deal of the people who are presently overloading github with one person created vibe coded projects would be just fine with the "CE" feature set.
I just rolled out CE in our small org, it is a nice step up from Free GitHub, there are Wikis, and no uncertainty about the runners. Founders like it better because their IP is on their own servers now.
I find it a bit concerning that this piece focusses so much on customers and shareholders... I know I don't pay, but perhaps sometime I will, and I am learning GitLab and applying at large orgs as GitLab consultant. All because of CE... So I hope it will stay. It is a nice and very complete on-ramp to EE.
