5e is fantastic. It presents the standard combat-centric D&D rules, and provides a lot of freedom for players and DMs to fill in whatever rules they find most enjoyable.
Levels 1-3 are designed for the express purpose of onboarding new players, so complaining that it doesn’t fully represent D&D, is pretty silly - it’s supposed to be simplified.
I will agree with the facts behind your comments on the skill system, if not the exaggerations. I would prefer a looser system, akin to those from Fate, Cypher or Daggerheart, to allow for more creative freedom.
D&D doesn’t suck - it’s a combat centric system, as it always has been.
