The people defending the devs here are crazy. Yes, correct, most games don’t even allow a name change, and ones that do generally have a cost to it. BUT there are some people that may not be familiar with these kinds of games and when you are presented with creating a name, you may have trouble thinking of one…and then right below you’re presented with “You can change your name later”, with only this statement, it’s generally safe to think “Oh, I don’t have to put much thought into it so I can start playing now, and change my name later!” later realizing “Oh…it cost money? Where was this information at the name change screen where it said I can change it later?”
Could a player have done more research on this? Sure, of course they could have, but it’s a devs job to make things like this clear to the player, things like this should not require you to have to search around and find an answer first.
