If the author of that email reads this I do hope you claim ownership so that I can reward your company with my patronage.
Maybe they just choose to be humble and let their actions do the talking!
Either way, this to me is speaking volumes to the type of company this is, but I do share your desire to know what the name of the company is.
I am not really impressed when a potential supplier is bad mouthing competition to get ahead of the pack. I would have a hard time trusting them, and being confident that at some stage they wouldn't bad mouth my company if I was no longer a client for XYZ reason later on....
