That was the 90’s, the QA was harder to do but actually done sometimes.

QA then was taken pretty seriously because, unlike today, they could not just issue a patch over the internet and expect their users to find, download, and install it. Much of the '90s was pre-internet era for many people, and it was certainly before today's world of having auto-updating apps, good search engines, etc.

In the 90's we also got to enjoy native apps.
