I think this kind of behaviour has been well documented among all the cloudmining services over the past years. What can you expect from centralised services, where transparency has been near zero for years and clients continue to invest without ever performing necessary due diligence?
In Via's defence, at least they seem to be offering a way out - though am sure at the $300 per share, they make profits and clients probably end up near break-even, with a lot of time wasted. Many others have just announced contract termination, or contract exchange. Contracts don't mean anything if the terms can be changed by the provider at any time - and guess what? They change it all the time.
Just another lesson in the very fat textbook of why cloud mining can never be profitable.
People will actually still never understand this, they're looking for the quick money which is something that they'll never get. But at least this is respectable enough to document it and to tell everybody, giving them a way out is also a wonderful thing to do and is something that they dont have to do, so a good thing to look at is at least they're doing that.
