That's a very common and very reasonable request, and given the size of Turkey, I don't think they'd prefer to lose the whole market there instead of having a lawyer in the country to deal with local legal requests.

Only when it's companies run by manchildren, like X and Rumble, they go on the internet to cry about censorship and shit when they pikachu-face-discover they have to follow a country's laws to operate in that country.

ps: You are already not buying games when you pay for them on Steam.

edit: To people downvoting: are you also mad that Valve/Epic/PSN/etc has to follow GDPR data regulations for EU citizens and keep representatives there, or is sovereignty only bad when a non–first-world country dares to claim it?
