It should be but it is not, in the bounty program the actual payout for owning accounts is 7k ish, that is assuming you met all the criteria and they still accepted the bug, which is not always the case.
Having said this attack was not best way to monetize this 0 day either, it looks like something else is happening behind the scenes we wont't know about, which is paying out the kind of money this attack should have been worth.
