It's a defect or multiple defects. I have 2016 MB and a mid-2017 touch bar MBP. So many keys have became unresponsive that I backspace most of the letters I type; A torture that you can't let your frustration out on by typing heavily, lest your fingers bear the brunt (Newton's third law + shallow keys). My shiny new MBP began having these issues after about 2 months.

2nd gripe: I made the most unfortunate mistake of attempting to install Windows 10 through bootcamp. short story: windows f-d up during reboot, leaving me with a non-booting mac parition that I don't want to erase.

I thought I could repair it with Ubuntu, but...

Most aggrivatingly, there are no linux drivers for the keyboard on the MBP (due to the touch bar being a single unit with the keyboard) and you need more than one USB-C to USB converter if you want to both plug in a linux boot disk and a keyboard that actually works.

Far worse is the fact that there is no linux driver for the entire logic board (as it's a single unit with the keyboard and touch bar). No logic board means no access to the hard drive at all. So I can't fix the partition with a linux boot disk even if I do have multiple USB converters. Now both laptops are either used as bookends or to hold my coffee. So yeah, thanks Apple.

Yes, the keys get sticky. This is the first keyboard where they tell you to clean it with compressed air and in my experience it's required.
