Gitlab is far from a monopoly by any definition. The name for it is VC-backed capitalism. Burn through money to buy a market— run at a loss longer than your competitors can, then flip and start hiking prices once you are dominant. That was never a good strategy for Gitlab, though, so I’m surprised they took that road.

The goal of which is to seek monopoly or at worst stable oligopoly.

Anyway, GP was asking what you call it when you saturate/dominate a market, become the standard and then raise prices on your captured audience. This is definitional monopoly. VC-backed capitalism is a predictable symptom emerging from the possbility of such outcomes.
