It had far less of that at the start. It was a boiled frog effect for me. I realised I was just fighting through corporate trash to find a few gems, rather than filtering trash from a sea of gems.
The loss of 3rd party apps just gave me the impetus to jump ship.

I've fixed this several times with a bit of thick tape. It wasn't actually the button that had worn down, but the plastic stub that pressed it. A bit of extra material kept each working for months/years after.
My current mouse has this fix over a year back, and is still working reliably.
