I have a Sonos soundbar. It used to be nice. Now it automatically goes to sleep after a few minutes of tv inactivity. I now hate the device and the company.
My old M1 mbp used to feel super fast. A number of MacOs updates later it feels sluggish. I don't see anything better about MacOs of today vs. 3 years ago, literally NOTHING.
My apple tv now routinely drops airplay -- it used to work flawlessly.
Etc. etc. All those companies push shit updates to keep their existing engineering teams busy.
