If they were honest, they would call it Unfair Source. 'We get to put bully our users for two years, and then they can have their freedom" - what’s “”“fair”“” about that? Yes, I said bully, because they can put spyware, malware and bad features without anyone being able to redistribute a copy without the mal-features. So either you get bullied, or you wait two years before the software goes open source. But by the time it’s gone open source, the software will most likely be obsolete, because that’s the pace of modern software development. Completely stupid license. If you want to keep your freedom, stick to free software.

we’re carving a space for companies to safely share

To be fair, it’s no safer than being GPL etc. in that any license is only as useful as your ability to enforce it in court. For a bad actor, whether they violate a fair source license vs a GPL likely isn’t much of a concern at all.
