It is as simple as that.

Bitmine and Innosilicon worked together to produce the chips, so both of them have rights to produce/resell the chips.

But even as Bitmine had an early start on availability of chips and great cheap costs, they FAILED to deliver their system successfuly and on time.

So AFTER my systems of 60T RUNNING over 1 month, and start to sell to public, Bitmine's system still NOT seeying anywhere.

From pespective of marketing strategy, this accusation is just a tactic to slow down our sales.
