Who certifies it as kosher?
If it's not certified it's not Kosher?
I live in a community with tens of Thursday night Cholent places, none of which have a Hechsher. I don't buy from them, but obviously they have customers or else they wouldn't be in business. Are all of those customers eating Treif? No, they just have lower standards than I do. (Bad example because Halacha says you can't buy from a business without a Hechsher, but you get the point)
Again, I'm kinda playing Devil's Advocate here, but I just think that it's up to an individual to decide if it meets his standards rather than make blanket statements such as "Don't buy Mishpacha because I don't like their Hashkafos".
