Citation needed. I remember Ubuntu sneaking in some stuff a couple of years ago[0], but most of the mainstream distros have a clean track record. What are you referring to exactly?
What problems have you encountered on Fedora that were caused by a distro upgrade? Asking this because I've been using Fedora for years across different machines and can't recall any breakages that were direct consequences of an upgrade, though I usually apply it a month or two after the release date, so maybe there are early kinks that get resolved by that time.
I've been in-place upgrading my Fedora install for about 7 years. Or is it 10? IDR. As far as I remember the upgrade has always succeeded. Sometimes things are broken afterwards because software I liked got removed or something, but I never got locked out or the operating system unusable.
