Alpha testing is, by definition, testing on unreleased code. Even though they are offering the testing to some select group of people, it’s still considered un-released.
The only reason you’d make someone sign a legally binding document saying “you’re not allowed to say bad things” is because you know there are bad things to say.
False dichotomy. There is also the possibility that you realize, from experience, that when you start introducing users, unexpected shit happens.
They could do the alpha testing completely internally, or they could give some super fans pre-access with more restrictions on what they are allowed to say. Would I prefer they be able to speak their mind? Of course. But I get why the company would do this and it’s really a complete non-issue.
Sure, they could do an NDA, or they could also get free publicity. It’s reasonable for them to choose the latter, and if you don’t like it, it’s reasonable for you to wait for release.
Preventing people from talking about the bad things won’t magically get rid of the bad things.
Yeah, that’s pretty clearly not the point. They presumably want to fix the bugs without them counting against them in the court of public opinion.
