It had been a thing since mobile phones existed.
Pre-paid cards that required paying for unlocking the phone firmware, eventually forbidden on EU countries.
Vodafone famously had their own firmware on Nokia N95 in Germany that disabled tethering,....
It starts by regular people being trained to accept that lack of quality and restrictions are normal in digital world.
Depends on how the rollout of mobile networking historically went in a particular country. (Mostly, from what I can see, if it was the entrenched landline monopolists from the start or if they had to outcompete a few upstarts first.) In some places (Russia, Ukraine) you have to explain to people what a carrier-locked phone even is, and they get (understandably) appalled at the concept. Others (Turkey) have went as far as to have infra to IMEI-block you after you spend too much time in the country until you pay up.
Turkey situation is different. IMEI block is here to collect exorbitant taxes.
This have nothing to do with carriers.
