Based on this comment alone (we are not provided with the name of Diehl's company), it sounds like Diehl has opted to support a blockchain-based business that complies with the law instead of one that flouts it. That is smart decision-making.

IMO, this comment suffers from a misunderstanding of the term "conflict of interest". To me, the conflict would be that Diehl is presenting himself as a source of objective reporting on the negatives surrounding "blockchain" but in fact he himself is invested in it. As readers we might question whether he is downplaying the negatives. Yet when one Googles his name, we find the opposite.
