Yes. Everyone and their mother posted that thinking they were clever.

It is also very telling that the concerns over warranties came up when:

1. The previous owner of the company who everyone knew and trusted died
2. There was active concern over the future of the company
3. The person trying to sell them that is a deranged lunatic with a sex pest best friend
4. The company is actively under threat of a hostile takeover spearheaded by people who might have killed the previous owner.

Are warranties foolproof? no. But they give you something so that you are only deciding if a lawyer is worth it when circumstances change significantly. Rather than by default any time anything goes wrong.
