You can disagree. But be wrong.Disagree on both counts
The problem with 4e was that many didn't think it was D&D and it was released before the tech it wanted exist.
Wrong again .That seems highly unlikely.
Maybe with non-inflation adjusted USD, like how Hollywood likes to falsely claim “record” box office for things like Avatar, that actually sold far fewer seats than the real top blockbuster movies like “Gone with the Wind“ and the original “Star Wars”.
4e was the highest selling RPG until 5e. 4e was never outsold. 4e didn't sell the crazy high numbers WOTC wanted.
That's the issue.
The RPG has to make equal or more than what the publisher wants. That could be 1 million, 10 million, 50 million, 100 million, 500 million or 1 billion.
