No, that is terrible advice. People will try to throw ridiculous things in contracts, but as a business owner, it is your responsibility to read them, and negotiate adjustments. It is also your responsibility to know what is/is not acceptable for your business, and know when to walk away from a negotiation.

Sure, but sometimes it's worth the risk to sign these contracts to land a big customer, even if they are unfavorable and may ruin your business. Especially if the alternative is no viable business at all (which would be the case for me).
