Did you call them official D&D rules? Even if you did and nothing happened, that is not the criteria that decides whether something is legal.
Why did you immediately move those goal-posts? I have published DnD Rules, per your definition, but I never called them "Official DnD Rules" because they are not official. But since when have I ever once claimed that? I claimed you could make DnD Rules, not that you could make Official DnD Rules.
Just like I can write an Iron Man story, but I can't write an Official Iron Man story.
to confuse the issue? This is not the first time you did, just the first time I am mentioning it
No, I actually had a whole paragraph explaining why I did it. Good reading.
lore and story are not rules, the subset refers to only having an example feat and one example subclass per class, etc.
In the 2014 rules, feats are an optional rule. Additionally, what is the value in copying a feat verbatim that you already have? It would be noted that both Tasha's and Xanathars reprinted zero feats from the 2014 PHB and only printed anything regarding to the subclasses when altering them, such as Tasha's revised Beastmaster Ranger.
The "subset" then excludes the material most useless to someone who is offering a new product. You'd note that, despite being in the SRD, no one who makes 5e compatible products has reprinted the Evoker Wizard. Because there is no point in doing so. That is already available and owned by their target audience.
because the setting is not part of the ruleset and D&D was always setting agnostic. Changing the rules however means it no longer is D&D, but probably something close enough that you calling it D&D is fine, you publishing it under that name is not however. As I said, this is a legal argument.
And I have never really been making a "legal" argument. You can make the claim that it is illegal to make a game based on the DnD ruleset without the SRD in place... but that claim has never once been tested in a court of law. We do not actually know if it is illegal, because no one has taken anyone to court over it. In part because the little guys can't afford it, but also because the big guys can't afford it. If it is ever found to not be illegal to copy rules, things get very very messy for companies like WotC.
But again, I've never been terribly interested in this from a legal perspective.
yea, 5e is separate from all of them and they are all compatible with it, including D&D 5e.
I again disagree with the statement that 5e is seperate from D&D 5e. It is a rather simple problem. 5e stands for "5th edition". We then would need to ask "the fifth edition of what?" It isn't the 5th edition of Nancy Drew's Cookbook for Detectives. It is the 5th edition of Dungeons and Dragons. The 5e SRD is the core rules, stripped to the fundamental system, of Dungeons and Dragons 5th edition, it is not a seperate entity that D&D 5e just so happens to be compatible with.
what you do at your table is only of interest to your table, once you go beyond that, you will get in trouble if you distribute something under the name D&D, assuming WotC notices it
What do you mean "under the name D&D"? IF I were to claim "this is an official DnD product" then sure, I could get in trouble for that. But I've never said that, it would be a demonstrable false claim. It is however, a set of rules for running the TTRPG DnD 5th edition. That is true, while not being an officially licensed product. And it is much, much murkier if I can get in trouble for making something to be used with a system, while not claiming it was officially sanctioned.
I can get in trouble for selling Acetaminophen and calling it Tylenol, if I am not the company behind Tylenol. But I can't get in trouble for selling a generic Acetaminophen (assuming I am properly licensed to sell drugs in the US at all.)
