D&D has got several romantic couples, for example characters from Dragonlance, or Drizzt and Cattie-Brite.
D&D should be ideologically neutral. Other franchises from the entertaiment industry weren't and the audience punished them very hardly. And let's remember there are other markets where the rules about censorship may be radically different. You can't imagine how irritating it is when an author thinks he knows more than you, but he doesn't. The art of persuasion lies in not trying to embarrass the other person or force them to agree with you.
Let's remember in lots of cases the books are bought by the parents to play with their own children.
No one is forced to agree Hasbro or WotC's choices but nobody is going to forbid you to play with the old sourcebooks you bought time ago, or with some retroclon. If you don't like the age of mortals from Dragonlance, for example, you are totally free to create an alternate timeline where that didn't happen.
We have got lots of new ideas in DMGuild, new settings appearing in kickstarter, and new classes and PC species being published thanks GMBinder.
We can chat like civiliced people for example about the reason because I think 3.5 Draconomicon was better than 5e Fizban's guide of dragons dued 3.5 Dr had got more crunch. Let's keep the calm.
My corcern is if WotC is too late to publish new classes after the artificer and psion then that space could be occupied by 3PPs.
