You make excellent points. Personally, I rarely have a problem paying for proper DLC (and buy proper DLC I mean, additional story content that wasn't obviously cynically cut from the OG game). Notable past examples for GTA, stuff like 'The Ballad of Gay Tony' were amazing expansions.

Also sticking with GTA, they're a good example of bad practice nowadays (imo). They pivoted to online-only DLC once they realised how lucrative a pay-to-play system can be when leveraged against not being bullied by players with more disposable income. There was amazing single-player content in dev for GTA5 and they cut it to focus on MP. Worse, they left the dregs of that content in the game, allowed a 'GTA5 mystery' concept to flourish and left people hunting for the mystery thinking they were going to find something like GTA4's bigfoot. Knowing all along it didn't exist. But of course, happy that people were still playing and hoping they would get bored and try online mode.
