Re: I give SuperMicro the benefit of the doubt.
"Not clear they can sue unless they can prove some sort of conspiracy. "
Of course they can sue. It is unlikely they would win a libel suit, since it would be very hard to prove malice. However, if a court ruled "there is not one bit of evidence that Bloomberg's facts are true, but Apple / Amazon etc. cannot prove malice", the companies would be happy with that.
