Strangely enough that's more than possible. It's always harder to find good news than bad news about a supplier. As soon as someone isn't happy, the whole world can usually read about it these days, but when they are happy, not many run to tell everyone about it, just the way people are for the most part.
My theory, if there's no good new then that's not important. It's the bad news that you have to worry about and if that's also missing, then that's a positive sign to me : )
