The question itself isn't really the issue (these are very serious allegations) - but if you read between the lines, my issue is with what the OP actually wants. Because, all you'll get on pprune is perhaps a clarification of what the rumours/allegations themselves actually are, as has happened here (Guns's link). With something of this magnitude, dealing with the business deals of upper management, I believe there is absolutely no way you will get any more concrete info here than you would reading any readily available newspaper. And so far, nobody has any info at all, other than a link restating the cause of the original question. From a newspaper. Which proves my point, so far at least.
Let me summarise - whilst the question (Is it true?) is valid, there is no point asking it here - a verifiable answer (ie, Yes it is true because of x, y, and z) will not, IMHO be forthcoming. Only time will tell.
