I can't be bothered to bother that GitLab has junior people, even to the extend that it's the first "real job" for some of them. We hire people for their first "real job" all the time -- someone has to!
Of course, the problem is not that some people are junior. The problem is that most people are junior, because, ironically, unless you live in one of the most expensive cities on the planet, their compensation is not commensurate with what an experienced developer can make in any first-world market.
When you have an inexperienced crew running your tech, you get a lot of very preventable issues, which sometimes approach apocalyptic scale (like GitLab's February data loss). That's fine for some businesses, but it shouldn't be fine for something as important as GitLab.
