Wii U and Xbox One may have done a poor job at asserting themselves, so let's compare it to one that did a far better job, the Nintendo Wii. While the Wii was a critical and commercial success, core 'gamers' never embraced it. Mocked it, sure. Lambasted it, definitely. But never truly embraced it. Nintendo did work hard to make a case for the Wii, clearly a good enough case that the console sold a ridiculous number of units - but all gamers did was clamour for a second failing, a second Gamecube. Even now, people on GAF regularly ask for Nintendo to make a straightforward console, instead of even trying to break the mould. That's sad.
Eh, Nintendo tried to make a case for it, the problem was the majority of the cases where the motion controls met success in the mass market was with more casual games, the Wii Fits and the like. Which, when you boil it down was ultimately a mass of arguably broken or outright easy to exploit minigames that the motion control barely worked for, with only Tennis really being any degree of particularly competent (And even then you could still game it if you knew how).
When they tried it for the more core games? Tended to be either outright in the way, or otherwise a nuisance where more traditional controls would have worked better. Half of this was the horrendous control design, which had far too few buttons in the general Nunchuck format. Like there's a reason these games that try to use it have notable camera control issues, the format just wasn't up to snuff because there were too few input options compared to more traditional controllers.
The other half was outright terrible design decisions for which control formats to use. Like in Other M. Horrendous story aside, the guy who suggested not to use a nunchuck format for a game that was practically perfect for it should have been fired. Tri at least got it right, you had a bunch of terrible options but ultimately it gave the users a choice in the matter at least, and if you forced over the cash for the classic controller you could just play it the way it was meant to be played anyway.
Sure Nintendo tried to make it work, but ultimately all they did was rush motion controls before they were ready, had to release the plus to get it to marginally work closer to what they originally sold people on (And really even that didn't completely fix matters), and ultimately drive it into the ground as a result since they burned their bridges chasing the casual crowd success they lucked into.
Which is a shame because honestly? Motion controls can work if done correctly. I've said it before and I'll say it again, there was only one game that actually sold me on motion controls, and that was Final Fantasy Crystal Chronicles Crystal Bearers, or FFCCCB since that's a mouthful. That was a brilliantly designed game with a really cool idea implemented in a really clever way that let you the player figure out just what you could do with such a simple ability (Though the lack of success is probably because too many didn't figure it out since it wasn't particularly clear on the matter).
And even that game still had camera issues since the Wiimote was badly designed for that sort of thing. I'd suspect if it were done for the move that would be less of a problem since it had more control options available but I don't imagine they'd ever think to port it. Which is a shame because I really liked that game and would love to see the promising idea expanded in a sequel.
