Given that it's a public-source project it probably will even have build instructions and an appropriate 1-step build, in which case it'd pretty much be begging for people to pirate it.
Of course, we all love github, and we value development time, so we wouldn't do that. But I wouldn't be surprised if a lot of people pirated it, if public build-able source were the case.
Maybe they'll resort to the time tested registration keys scheme.
We can speculate all night long, but at the end of the day, it won't mean anything until they decide on it and tell us how they want to proceed so that we can...
