Well, let's see.
Sales = quality; other games sell less, so they are clearly lower quality, while D&D sells more, and is thus better quality. "A better...play experience".
Popularity (which, for products, really is pretty much identical to sales) = quality. If it is played a lot, it must be good, otherwise people wouldn't play it.
"5e is already the best it can be because it makes ridiculous amounts of money. It is hubris to argue that changes any individual person likes could improve how much money 5e made, therefore, 5e is the best it can be." Again, sales = quality.
I welcome any corrections the above posters would like to make that disclaim the connection between popularity/sales and quality.

5e has made more money than any edition of D&D ever, it's still making gobs of money. Saying they would have made EVEN MORE money if they'd just done X (which happens to align with "my" tastes) is pure unsupportable hubris.
There is a reason they abandoned modular design (which is essentially what you are advocating for) - and the decision (though I personally am sad about it) seems to be working quite well for them.
For My part. I absolutely did not say that sales mean quality! I was responding to the claim that "had they just done X they would have made even more money..." - a completely different argument.
Though I will also add - 5e IS a quality game/product, which is completely separate from the "it's made a lot of money..." argument. It has, IMO, some serious blind spots and ways it can be improved upon. But to claim it is not a quality product (which by NO MEANS implies perfection, or even close) is a pretty tall order.
