We don't talk about Pun-Pun
Coming off of 3.5, there was a strong "RAW is sacred" sentiment among D&D players, many of whom were resistant to DM's just arbitrarily changing the rules. So I can certainly see that even if the books explicitly said (and they did) you could make houserules, why players (and even some DM's) would reject them.
(A good example of this was spells that dealt fire damage saying they targeted creatures but not objects, or were silent about environmental damage. The books did in fact tell the DM that you can certainly allow someone to light things on fire with a fire spell, but that the rules for most powers were written with their intended use case in mind- combat. The DMG had, however, examples of how much damage things in the environment could do, like lighting things on fire.
But you know, maybe "nobody reads the DMG" isn't a uniquely 5e thing.)
Some people say this was player entitlement "how dare you nerf my power" or a reaction to DM overreach "I don't like that your character can do this thing in my game so you can't". Like with most things, it was somewhere in the middle.
