Well the question to me, is that why the hell they LET BITMAIN and Baikal mine with their ASIC miners since last summer?
Now they changing their pow when these miners goin to public.... i dont know who is the bigger pr*ck...
There is no way to be sure who/what is mining what. For all the Monero team knew, it was a private farm of FPGAs. I doubt anyone was particularly suspicious until presale announcements started happening.
