Unfortunately I've found there often needs to be separate internal and external version numbers.

An internal rewrite where all the "old bugs" are fixed, but minimal new features are added may feel like a 2.0 for those who worked on it, but for external customers it's the same tool, with the same functionality, just maybe looks a little different.

A 2.0 is often heralded with marketing fanfare, so it needs justification.

I'm not saying it's right, or that one rule fits all; I've seen it first hand and feel your pain.

And on the flip side, sometimes internal version 11.3 is a boring release with only small changes since 11.2, but if one of those changes was a feature that marketing cares about then bumping to The New Exciting 12 may be in order.

Opposite(?) example is Windows NT 5.1 / 6.1
