I don't know what he's saying, but I would say that you should not have your product depend on something that is subject to change. Thus, although the vendor can do wrong by changing their product API when it is in Beta, it's still ultimately your fault for relying on something that hasn't had a stable release. Although I get what people are saying about Beta products, the truth is that different vendors use the term "Beta" with different levels of precision, and thus should not typically be trusted not to pull the rug out from under you in some way if they haven't firmly committed to stability.
