Yup, this is it for GitLab. They've never been profitable. I'm honestly surprised they went this long without layoffs.
And it is no wonder they have issues when their customer support is hostile. I used to pay for Gitlab but switched to the community edition after having to deal with their support over billing issues. Easier to use the free version than the paid version. Making money does not seem to be a priority.
Same here situation here (went from paid to free for a similar reason). We are a small team, so we don't represent a lot of $, but it's changed how I perceive Gitlab as a company, and it also means I won't recommend them anymore to clients.
