You never ever had a single software change its workflow?
Radical workflow changes with no recourse is the standard in proprietary software, not so much in FOSS.
Jokes aside: yes, I can see how it's technically possible to never experience a workflow change. But also using the same tools at work, your kids school, family you help etc. I just find not very probable.
The great Gnome 3 rollout did this for me... to be fair I guess that was a decision of the distributions, but it was in concert with the developers who decided to make a hard changeover, EOL the gnome 2 line there and then, and (deliberately?) scupper the possibility of installing both 2 and 3 on the same system.
Either way it sucked and that pushed me to Xfce, which I still use on linux. But it goes to show it can happen in FOSS.
