Journey and Flower weren't published by them on IOS/PC, it doesn't look like they had much to do with the ports at all, except perhaps allowing their existence (don't know who owns what).
Considering Sony owned the IPs even for games of their most trusted partner (Insomniac) I would bet Flower and Journey are Sony owned IP, so they get a cut of the port even if they don't publish them.
