(All personal opinion, etc.)
I'm not actually sure what a better way to square the circle of not making the large entities that have developed a weird patronage relationship with open source projects run away while also avoiding the kinds of problem that the GPLv3 and AGPL are hoping to deal with, would be. Limiting the virality scope might be beneficial there, but I'm not sure how you would word that in a way that's not gameable.
It feels like we've wound up in a weird position where because so many GPLv2 projects moved to GPLv3, companies were startled into paying attention to the risks involved in a new license with open questions about how it would shake out in actual courts, as well as being jolted to the very real possibility it could happen again, and took the path of risk reduction by moving toward platforms where that couldn't happen.
You might compare it to everyone pointing to Solaris's source closing as a reason to not trust Oracle about MySQL's license remaining GPLv2. (As it turned out, so far, they haven't changed the license, but there was certainly a lot of fearmongering about that at the time.)
So I think I agree that it's not so much a coordinated effort to steer anything as the direct effects of companies avoiding funding that space, as well as the knock-on effect that anyone whose goals involve large companies using their product and leveraging that avoids picking a license that precludes that in turn.
