I'm really confused at the vitriol in the comments, does this license not become a true OSS license after the change period? IANAL but that seems to be the case to me. It's so confusing what part of this is frustrating? I think keeping a 36 month buffer of features to maintain an a commercially viable edge to fund work on a project is extremely reasonable. It seems like a really good and virtuous model.

Patents and Copyrights are more than an order of magnitude more temporally restrictive. This is great stuff, I hope it proves to be commercially viable and sees broader adoption.
