Whether or not software can be finished with 0 bugs is sort of irrelevant. Windows and other software users use most will basically never be "finished".
The updates that are causing the fever are not just "bugfixes", they are the current state of living software--always expanding and improving (at least in intent). The fact users see software that hasn't been updated as dead is a reflection of their learned expectations. And they are correct, it likely is dead in the "no longer improving as my other software is" sense.
The real issue I have is how shitty most update processes are. Thanks for rebooting my PC Win 10, yes Sublime Text, please tell me again in a dialog that there is an update, etc. Some apps have done much better here like Chrome and Discord, but it is not an easy thing to build.
