GitLab already proved the type of company they are when a few years ago their back ups didn't work and they lost code. They showed what they could do by transparently showing the world how they were fixing their mistake. And since then the software and service has been brilliant.
The people who work there could be genetically modified budgies who weigh 50kg but are 7ft tall and all love Bulgarian Folk Trance music. It really doesn't matter. What matters is the product they provide you with and whether the choice of that software will get you sacked in the morning.
