TBF, jano is actually respected in his field outside of this community. His criticism of this lab was patently valid and fair.
Success breeds envy; there will always be scorn in the hearts of those that failed to seize upon that idea that they had once (or maybe not even so), and who lacked the education and will to action, including risk tolerance, to make that idea into a reality.
This is what jano seems to have done quite successfully with HP/LC analysis at considerable risk, considering the expense of that equipment and the uncertainties of a market that hadn't really existed. In a way he willed the primordial concept of AAS harm reduction into a tangible thing, a service.
I cannot say what his motivations are on this laboratory, whether legitimate concern, or at least some part business, but I do think that he'd not bring attention to a competitor if that competitor were a superior one.
