Pointing out that research was paid for by an organization that has an inherent conflict of interest is an extremely valid argument. It doesn't necessarily mean that the research was biased or shoddy, but it absolutely should cause us to take their conclusions with a healthy helping of salt.

You will still need to point out the actual ignored facts or false claim to substantiate the bias claim, otherwise it is an extremely cheap argument that everyone else could use the same argument as most people represent some interest group.
