It's easy to write code and release it with a 'use at your own risk' license on it.

Offering support and accepting liability for problems with your code isn't fun or easy.

No one accepts liability for software problems. Not free software developers, not Microsoft, not Google, not Oracle.

Mostly only OEMs of non-computer equipment, such as Boeing, warranty physical products that include software. For code that doesn't run in planes or cars or other machines -- there is no warranty.
