The one situation I can imagine the Touchbar brightness concerning me is when I'm on a plane. They always turn the cabin lights out, and I'm aware that I need to turn the brightness right down on my laptop when I'm in economy class, so I don't bother those around me. A quiet keyboard is also important on a plane.
I've not used newer Macs except in the store, so I don't know if the touchbar brightness is actually an issue or not. I definitely like my physical volume buttons for making sure my laptop is muted while flying though.
I am convinced that the only people complaining about this have either never used this laptop or have such sensitive eyes that daytime light would render them permanently blind. And I say this as someone who was excited by the possibilities of the Touch Bar but have so far been underwhelmed and wants to go back to the physical keys.
Does it really help the conversation to say things like this?

It's really not bright. I'd guess it's probably less bright than the keyboard backlight, which also isn't bright (but is at least dimmable). It's so not bright that I've literally never noticed the thing at night in well over a year of regular use. Whatever number of lumens it outputs is so far below the brightness of the main display that it's all but unnoticeable in use.
I cover my monitor's power LED as well as the status screen on the receiver for my wireless headset. I run F.lux on the reddest settings when I'm within 1-2 hours of bedtime. (and after that I don't run any screens)
I have no issues with daylight brightness, but must carefully control lighting at night due to a broken circadian rhythm. Trust me, I don't need to own it to know that it's too bright. Especially if F.lux is not supported, which it is not last time I checked.
If you're not willing to consider that your concern is unfounded, then you shouldn't be offended when other people dismiss your concern.
Trust me, for me, it's not an unfounded concern.
