I think it strongly depends on how it's done and how it plays into the feeling of the game. Certain kinds of level scaling can feel pretty cheap, for example, because they kind of work against the feeling of progression you get in the game. Similarly a game obviously making things easier for you can feel like it's cheapening the satisfaction of improving at the game, though how important this is varies from person to person.

But done well, it can much more reliably create the feeling of being just on the edge of failure but pulling through, which is really satisfying in a lot of games. L4D did this, but Helldivers 2 for example also has a lot of game design focused on creating this kind of feeling.
