I blame browsers for their out of control versioning.
Chrome is on version 118 now and gets a bump roughly every 6 months. Firefox is 4 years older, yet they started following the same rapid versioning at version 5 to "keep up" with Chrome which was already on version 12 but a younger browser.
2011 is actually the same year Firefox started their rapid versioning to try and match Chrome. There was definitely a shift in versioning styles around then.
