1) I don't believe it. This claim came as a response to people who said there is no difference between their upgraded headset and unupgraded demo units from Bose store. Then others started claiming that even QC25 (which is not upgradeable) has been downgraded. Sorry, but we are getting into conspiracy theory realm here. Also notice how the cutoff date of 'good' headsets keeps changing - first it was 2017, then Oct 2016 and finally August?
3) There were various methods (for example downgrading to 1.0.6 then upgrading to 1.3.2), but they all seem to work for some people and don't work for others
4) That's right. I have not noticed any differences between 1.0.6, 1.2.10 and 1.3.2 (high) setting. I generally tested it by running something like 'bar ambience' on youtube for several minutes, setting volume to where I could barely hear it, doing firmware update and then listening for several minutes again.

Upon finally having the chance to objectively sit and listen to these things in different environments, I'm starting to think that maybe I should just put these on eBay and invest in a pair of QC30's instead.
I've always loved my Bose around ear headphones. I have since my first paid of Bose AE2's many moons ago, but always having to worry about how the ANC is performing on these is starting to wear me out. They definitely still aren't the same headphones I have been using. I still love the sound, but I feel like I can get the same sound and noise blocking out of my SoundTrue Ultra. In fact, I feel like the Ultra's block the lawnmower noise better than the QC 35's now.

POEOPLE WITH 1.0.6 or OLDER FIRMWARE SHOULD NOT UPGRADE!!!!!
reverting back to 1.0.6 will no longer bring back the good old ANC and sound quality.
I'm SURE they have modified the 1.0.6 or the new firmware ruines something which reverting back can not correct.
Your headphone becomes useless with the latest firmware. Weak ANC and countinous hissing noise is noticable immidiately after upgrade.

Great review, thank you! Just changed 1.3.2 for 1.0.6 - must say it indeed seems Bose got it right this time, difference with 1.0.6 in base performance is indeed minimal and having the ability to set the NC levels is great.

For the record:
Received my QC35 today, Built April 2017, stock 1.0.6.
I used a dB noise meter on iphone and put the headset microphone in between my ear and the right earcup. Then I tested stock 1.0.6 and upgraded 1.3.2 with some Youtube clips of a waterfall and airplane cabin sound (didn't move my head between the firmware update).
with ANC: 58,8-59,9
with ANC: 57,3-59,0
with ANC: 58,4-59,8
with ANC: 57,2-57,8
Result: basically no difference. I think the firmware update drama is done for me here 😉
Some people surely will say that headsets manufactured after October 2016 have a new "less good" 1.0.6, but unless I can test that myself I'll disregard it for now.
