People did NOT buy INTO beta! Beta access (unpayed tester job) was a goodie to a PRE-Purchase of a game that included OFFLINE capability... If you carefully read the terms on the
store, which must have been posted hundreds of times, carefully, there are no uncertain terms for cancelling the order!
"or from the day of the conclusion of the contract, in the case of services or digital content not supplied in a tangible medium", as in receiving access to the final game you actually bought (opposed to a testing framework for "invaluable feedback and tracking down bugs (FDs own words).
Further:
"You may cancel a pre-order for a Digital Product up to and including the day before the release date of the relevant Digital Product by contacting Customer Services clearly stating your order number and item(s) to be cancelled." the RELEVANT product in this case being the actual game! Again not what we used to HELP Frontier Developers to find bugs, test game mechanics etc.
Also keep in mind, usually play testers are HIRED to test these things and help in checking performance and stability.
In our case with the added benefit of thousands of different hardware compositions, which is always tough on developers who do in-house testing.
To be clear about that, I have no problem with help testing and not getting payed for my work, as in return, I could have a look at what parts of the final product may look like.
Just understand, people are rightfully angry about that last minute decision. If they choose to get the pre-order cancelled and want a refund I think it is the least FD should do. If FD does not refund with "evasive" answers, these customers are in their legal rights to take further actions, as in revoking payment through credit cards and fight it out in a court.
The later being not good for either FD nor the remaining community as it can easily end in financial desaster!
Just my thoughts...
