Only someone with a paid agenda or a recent brainosuction would ignore these simple facts:
1. BU miners have already threatened to attack and destroy the non-BU chain after a split, this is documented
2. BU miners under Bitmain lead, have ASICBOOST, so they can invoke a
30% gain at any given time, on their own miners3. Now Antbleed has been revealed; a method that, until 48 hours ago, could have been used to destroy everyone elses Antminer on the planet at their discretion
There is no certainty, but there is certainly a possibility, to combine 2+3, to achieve 1, which would be the destruction of the alternative chain, at least a temporary disruption, that could be the edge required to turn their BU chain into the winner.
Am I paranoid again?

I'm not an expert like franky1 or Lauda, but it certainly sounds serious to me. It sounds like a "doom switch" for sure. But, I think that its revelation will have foiled the plot if there was a plot at all. So, I think it's not so big of a deal now that it has been exposed. It sure is an intriguing situation though.
