It's certainly only a part of games, but this also happens outside of games like Fortnite.
For example, one of my favorite games is Celeste, a fully offline, single player platformer that's about 18 months old. They've had a lot of releases[1], and at least one of them sounded like, to me, like a decision that was made purely because it was easier to implement technically. (I won't get into it here because it's pretty off-topic, but if anyone is interested, I can elaborate. It's "The Prologue Dash cutscene is skippable") There's also one more major content update coming that appears to have new mechanics, and it's already late. That said the game is amazing and I don't fault them for any of that at all...
