You've got a point there but no proper sponsor would terminate the contract because of one poor weekend...
There are reports that their twitter account could have been hacked.
But at any case, this "Rich Energy" was shady from the very beginning, nobody knows who they are and where the money is coming from (IF Haas actually got any money yet), it's just a solo bearded guy, the drinks that they are supposed to be selling aren't really available anywhere, they stole a logo of Whyte Bikes and are in court because of that, so if this termination of contract is true, it's probably because they are trying to hide their dodgy financials from the court.
