And those people would be worried, why? It's a pre beta...
As pointed out, actual Beta testers already know this stuff. And more importantly, will simply reach out and grab the latest build. Something they would do as a matter of course. So you're absolutely right, people *shouldn't* be worried about a time bomb that exists in a pre-beta release illegally obtained through torrents.
But somewhere... somehow... somebody... is going to turn "Oh well, my toy doesn't work any more"
into a diatribe on "The Endless Ways MSFT Screw People"
And the really sad part is there exist other individuals who will take the already deeply flawed pretext, twist it beyond all recognition, and run with it like it's God's Own Truth.
