I've beta tested release 1.5 of a game, and not been selected to test 1.6. It's not that uncommon to switch testers, especially if they haven't been helpful (and judging by that guy's opinions, I doubt it was that helpful of feedback provided)
Okay, that's a fair point. Given that information, it seems risky to drop playtesters midway through the process, especially since if you drop them because you don't like their feedback it probably increases the chance of a leak.
