5E D&D is a great game. All the 5E haters can eat bananas.
I'll take the banana for my daiquiri...
...and all the 5e lovers can eat a bag of ebola soaked donkey dicks!

Yes, everyone, everywhere, likes D&D. Everyone--including lots of women--want to play D&D.
Unless you're selling tickets to an orgy, "lots of women" ain't a selling point!!
I doubt "everyone" likes D&D or wants to play it. As for fantasy fans who aren't yet roleplayers, most will join a good group with a fun GM regardless of the system being used. It's no harder to get a Game of Thrones fan into a D&D group than into a Palladium Fantasy group since they don't know anything about the hobby other than hoping this RPG thing will be as fun as their fav show.
No one gives a fuck about some obscure circle jerk game that you like. Yes, that's right. Obscure, forgotten games will sit there and collect dust, or even if you and a few of your friends play such an obscure game, the obscure games are still largely forgotten and ignored.
So what?
When did popularity mean anything? Is WotC sending you a check? Don't forget their retarded lead designer said 2A supporters aren't welcome in their hobby. Why support fucknuts who hate you?
5e's popularity means especially nothing when I can walk into a convention, declare I'm running XYZ and get 3-8 players to the table. Do I need 400 to show?
More importantly, why would I want 5e players at my table? I ain't got non-binary dwarves or trans-cat people as PCs and my adventure isn't about saving the Bearded Hambeast Princess from Trump Orcs.
They are forgotten in game stores; they are forgotten on major online stores; they are forgotten on college campuses; they are forgotten on popular You-Tube Channels.
College campuses? You mean that place where they screech about micro-aggressions and mispronouning? I'm sure even wankass 5e is too much for them without safety tools and a cry closet.
If a game store supports an RPG, its because that company supports a Living Campaign system that puts asses in seats in that store. Obviously, only the bigger companies can pull that off. But online stores? Kickstarter, Amazon and DriveThru all sell tons of obscure stuff.
And YouTube? If they are chasing clicks, of course they only want to go with The Current Thing. As soon as 6e is the Current Thing, all those click chasers will forget 5e existed.
