Worse is when some UX designers decide to improve a product that works well as it is only to make it worse and convoluted. This has been my experience more often than not, and my solution is to simply stop using such products. It sucks.

I'm often a power user. I know all the features and shortcuts of the tools I use. All too often, these get removed. I recall being on a feedback call with a UX study, and complaining about a feature I use, and many friend use, that was recently deleted from the product. "Oh, no one uses that" was the response from the UX/PM.
