Oh you guys are so mean to HTC... The fact is that they kept the devices similar so updating is faster. I mean the A9 unlocked works on everything but Verizon - and they bailed on using it for them instead of making it work...
HTC does software (and hardware) very well and has pushed to be the fastest at updating next to the pure Google phones. They fully support unlocking bootloaders via HTC Dev and have a great beta program via HTC Preview. Overall, HTC is doing lots right, but I think there is more to get right with the Note than the M9... Think about if your SPen stopped working after the update - or your LTE radio didn't work right...
It's better to take an extra week or two and make sure it's right. Remember that poor tweeting person only has a binder with 'things to say' in it. They may not actually know what the heck they are talking about.
