I don't think android wear is at that point yet.
Look at the history of android phones. The G1 was stock vanilla android. The OG Droid was the same. It wasn't until after the Droid blew up android's popularity that manufacturers started tinkering with their own skins. To me, it hasn't been that long in the world of android wear.
And, whether they like it or not, Moto and others have been backing off of heavily skinning their devices slowly but surely. Samsung is arguably the worst out of all of them, but even they have been VERY slowly toning TouchWiz down.
I think it's more a greedy powerplay on the part of the manufacturers. They see the potential of the market and are trying to get the biggest piece of the pie as quick as they can. Oversaturation isn't something that a fledgling tech needs. You start getting devices like the Gear S, that doesn't NEED a Samsung phone to function, but DOES need one to be setup when first booted up. I'm sure it also functions better with a Sammy phone, especially when you consider things like S Health, that my LG g watch doesn't integrate with.
I dislike this trend for the same reason other love it. I'm not a "brand snob" by any means. I want devices that work the same with each other, regardless of manufacturer. Ie, if I get a different phone, I expect my watch to work the same with the new one. If I get a new watch, I expect my phone to function the same with it.
While others have mentioned in threads about the Gear S that they wanted it because of their love for Samsung's devices, I run the other way because it runs Tizen and not android wear. That's not to say that I don't get where they're coming from completely, it's just not the way I feel.
I'm an android fan first and foremost, even if my last 3 phones have been made by Samsung. TouchWiz, for all complaints about it, does offer some useful functionality that I'm sure I'll miss when I move on from Samsung devices (which many will remember me saying I intend to do when I go to upgrade from the Note 4).
As someone who love tech, especially new tech, I read up and watch videos and know the difference between manufacturer skins, but (and I've said this before too) the more variations we get of this one great idea, the more confusing it's going to be for less tech-savvy folks who just want devices that work and work well, together.
Choices are wonderful and a big part of why so many of us love android, but too many can be overwhelming for the "average consumer."
