Those aren't excuses, but they are explanations. The competition from Adobe crashes a lot, too. It's not necessarily a competence or money thing.
Also, the windows taskbar in windows 11 crashes a couple times a day for me. And Microsoft is one of the biggest tech companies in the world. And, I'm assuming, very talented engineers worked on that taskbar.
“Vista bad ” comments on a forum supposedly frequented mostly by IT people is just plain ridiculous. If you think “Vista bad, 7 good” then you clearly need to reevaluate your understanding of computer technology.
And they do fix crash bugs. All the time. You can see that in the announcements they put out after each release. I think the general perception is that it is indeed becoming more robust as time goes on as new developers have come on board to help. The project is gaining momentum that it hadn't really had before.
