Hi Frank, That's a great post (and the Mailpile post is also a great discussion of the topic), thanks for sharing.
The GPL already has a clause which allows the owner (and downstream user) to defer, for 12 months, the full obligations of GPL - see this guy's take: https://github.com/zooko/tgppl/blob/master/COPYING.TGPPL-v2-draft.rst Our idea is a bit more startup-friendly - on the commercial side of the dual license, everyone can keep their improvements/extensions closed for up to the full duration of the time-bomb, but they then have to give it all back. As to enforceability, I'm guessing copying the language of GPL is hopefully sufficient. These things are rarely tested as far as I know, but I'm sure someone knows better than me.
