The software I use by numerous name vendors all the way up to microsoft include a “dislaimer” that I am forced to check understaning that they do not take responsibility for their software impairing my computer and possibly causing it to crash.
Disclaimers aren’t worth the electrons they’re displayed with. If you can prove their bugs harmed your computer or your business (ie cost you money) and you can muster up the lawyers (this can be the hard part if you’re going against MS, they have a lot of really good lawyers) you can sue them and beat them.
Here’s an exact conversation I’ve heard at my software company:
customer - every hour your software is down we’re losing a million dollars, do you understand what that means?
our guy - it means you can afford better lawyers than us, we’re working really hard on this issue and we’ll have a fix out to you as soon as possible
And that wasn’t even at the company I used to work at that had payroll running software. It can be very “exciting” to find out that if you don’t get a fix out to a customer by 8 AM they’ll be in violation of federal law and subject to massive fines, because we all know what direction feces rolls and who will actually be paying those fines.
