Is it trolling and I'm taking the bait ? Or are you annoyed because you like your Mac and can't stand other people not liking it ?
If the latter and you just like your mac, just be happy with it and forget it. 
What annoys me is that a majority of the critics are what we call "spec hunters" and don't need much of what they're complaining about. I've asked some of these folk to outline their workflow and how the new tMBP was injurious and the silence has been deafening.
But please don't say completely unproven things like "criticism comes from non-owner and non-professionals", this is just not right. And not helpful.
Agreed, but I'll temper it with the word "mostly."
I'm an owner, and definitely a professional : programmer, running VM, servers & the works.
This is Apple's worst machine, and I used Apple since 2006 now and I've been quite used to the scam attitude where they sell overpriced machines with crappy components ( personally I particularly didn't digest the "let's continue to sell crappy USB2 ports while the PC world is at USB3, and continue to do so for 2.5 years", or the HDMI which took time to birth ) .
I'm also a professional. I'm a photographer using the top tier cameras and PP software. I do very minor video work and also write. My wife is a wound care specialist using the new MBP to run hospital software. I also own last years 15" rMBP and these machines best it in every way I consider important to my work. MY work is the key here, because YOUR work has different requirements and I respect that. They didn't build it for YOU; they built it for a highly researched majority of users along with a long term marketing plan.
But :
1) Sacrificing negligible, impossible to "feel", gains on weight and size for a much less powerful battery is just plain stupid.
NOT stupid for marketing.
2) Removing magsafe is unforgivable. People who go to conferences, have dogs or kids are certainly all bitter about this change.
TONS of other notebooks, which are great in their own right, don't have MagSafe. MagSafe has always been an expensive problem for me. Happy to see it go. And if I attend a conference with dogs, I can add MagSafe via a cheap adapter.
3) Adapter gate : The idea that your machine is going to look ridiculous for the next 3 years until you renew all your peripherals so that in 3 years, once renewed, you can say "look, no adapters" to the few people who won't have ONE USB-C ports on their PC is just preposterous. Stupid, even.
How does my machine look ridiculous? Who's looking? This is just a non issue that I can't believe anyone cares about. I always needed a car reader. I still do. So no I have a few tiny USB adapters and a USB-C to DP for my 4K monitors. Everything works and my tethered D810 camera works better.
4) Also, no lightning port to connect your iPhone7, are you for real ??
I don't use the iPhone since adopting the more flexible Android phones, but I believe a cheap cable solves this issue, no?
5) Power wise we're being given an old generation of processors. It would have been ok if the release happened last year, but not now that Kabylake line is being launched.
So wait a year if you want the latest Kabylake. The MBP lineup gets upgraded every year. No notebook is going to get it all perfect.
6) Nothing really interesting - the screen has average resolution, no 4k, no OLED, I really wish I would have had a "wow" factor. Instead I'm going to drool over the Yoga and its OLED screen.
OLED may have a wear issue and loses brightness. Apple stuck with a technology they've refined and as a photographer, I can tell you with authority that these new screens are a serious improvement over the 2015.
7) Keyboard is awful.
Well, that's your personal opinion. But I'm sure you've seen that many love it. If you can't adapt after a couple of weeks, I'd get rid of it. I can work faster on this non-mushy keyboard as can my wife, who types crazy fast.
8) Incredibly overpriced, and not impressive in terms of look AND hardware AND price compared to say, OLED Yoga, or Dell XPS15, or Razer Blade Stealth (the new one).
I won't get into a windows machine again. It's just that simple.
9) Still don't use the Touch Bar, it definitely start entering the "gimmick" phase for me. Especially at home where I use a stand.
I'm using it for video and it's pretty slick. My screenwriting software will also be using it. But it's too early to know if the TB is a winner/loser.
So no, negative comments come also from owners and professionals. Particularly from them.
Yours is among the very few "pro" complaints I've heard. I work in Hollywood and the adoption for the machines is rapid. Indie shooters are snapping them up for the brighter screens alone. This comes down to what sort of professional is in the picture, yes?
As to the switch to Windows, between the habits, the walled garden you put yourself in by using Apple, and the app you bought, it's not that easy.
Also personally Windows still has an awful "feel" to me, and poor design.
But be ****ing sure that if they could run macOS on any laptops (and I'm not talking hackintoshs), you could be sure professionals wouldn't be choosing the Apple ones.
