AFAIK it's not about Apple, but about other producers either polluting spectrum or plainly ignoring specs.
There was a post about Logitech not creating a lot of interference with their MX products (https://news.ycombinator.com/item?id=31939424). Interestingly enough getting rid of Logitech devices fixed most of the BT issues I had.
I have constant issues the single bluetooth device in myhouse - my Bose bluetooth QC-35s, and a google produced phone and google produced laptop which it connects to. Both of those groups should be able to get bluetooth right.
I can't even get my Airpods to work consistently with my iPad, or Pixel Buds to work consistently with my Pixel phone. And it gets exponentially worse if you try to connect to more than one device at a time, across vendors or even chipsets. Bluetooth is a hopeless mess.
That’s a good point and something I could look into (very) locally in my setup. Not many non-Apple devices around except a couple of cars and one mouse but yeah they could be causing problems.
