Using the GitLab calculator: If you are a developer in Medellín you are paid 3x less than if you are living in the Bay Area. If you are a customer in Medellín you pay the same as a customer in the Bay Area. In this case, "cost of living"[0] only applies to employees and not customers, which in my opinion says a lot about how much the company values their staff.

I appreciate the openness from GitLab on this matter though, they're pretty up-front about it so if you don't like it don't apply.

[0] When the word "cost of living" is mentioned but it's not reflected in the price for final users then you know you're about to get fucked.
