Probably a number of reasons: * Inertia. GitHub is mostly good enough most of the time. Actually in many areas it's actually downright fantastic. The few really rough areas aren't enough to justify throwing everything else away. * Trust & Stability. They've done a great job of cementing their credibility when it comes to taking uptime, performance, and security seriously. * Design. GitLab in particular still looks like a cheap knock-off. Having worked a number of years for a company that cares about design I've come to appreciate that the lack of attention to detail in things like this. * Insufficient appeal elsewhere. No alternatives clearly do everything I currently do + the things I want an order of magnitude better to justify a switching cost. The alternatives last time I looked largely appear to have some feature parity, some bits missing, the occasional thing better. It nets out at same same.
