I wouldn't say that things necessarily get worse with each update. I think new features get gradually added which make the software less accessible and/or harder to learn for beginners and/or impact performance.

I know, all of the things I said can be said to be the worsening of the software. But what many people think when they read that sentence is that just the simple act of updating software is detrimental to the user's needs. Which I don't think is true all the time.
