Summary
It looks like Apple might have been caught yet again nerfing the performance of one of their products with a software update, this time around reducing the effectiveness of noise cancelling on the AirPods Max.

My thoughts
While this may just be apple doing apple things, I find this instance especially egregious, if the alleged is true. If you go into a shop to try out different headphones and buy a pair based on the ANC you experience, and then the performance gets nerfed after a couple of weeks I would consider it misleading at best.
Making things worse, this update gets pushed without user interaction, so there's not even a way of opting out.
There's no statement out from Apple yet, so there may be a technical reason for this, but if there isn't and this is just their typical shenanigans, this looks really bad.
