Bullshit - or selective memory.
Back in the days, you bought a bunch of floppies, installed the software, and then spent years putting up with a lot of annoying bugs that required buying the next version of the software if you wanted to get rid of them. If they had fixed them, maybe.
Updating is great: if you have a slightly shitty piece of software, you stand a fair chance of getting corrections for free. The only annoying thing is when something that works great stops working great because the developer had a brainwave and decided to come up with Something Even Greater[tm] that turns out to suck. But then, you get that for free too, while before, again, you had to pay for the next version of the software to discover the sucky new feature that replaced the useful one.
