IAAL, and I do agree with you that contracts are overkill in many cases. However, if you are complaining publicly about another business breaking promises, I think it reflects poorly on you that you didn't get those promises in writing. That's what contracts are for, after all. You don't see Fortune 50 companies griping about shady suppliers on their blogs for a reason...

"contract" in law doesn't mean something written and signed, it is an agreement or implied agreement between two parties. This is a common misconception. The written requirement is only for certain types of binding agreements (land sales, etc.) and varies between jurisdictions. But in most business/service scenarios, oral agreements are just as binding as written agreements.

I was recently involved in a legal dispute where there was no written contract, but the trail of emails and communication was good enough to see judgement in our favor.

This is 100% correct, but getting it in writing is (almost) always better for enforceability. Also, notice that I never said anything about signatures...
