Exactly this. Making all prereleases public - even if a majority of the 25$ donors would agree - would be going back on a word, and that's unthinkable. But the campaign itself never outright said "If you don't donate at the 25$ level, you will not be able to play any of the public prereleases until ADOM 1.2.0 comes out (which might be a year or so)". Because if that should the case, I and anyone else who contributed or thought about contributing would have liked to know beforehand.
