Apparently: They decided they'd made a mistake with the licensing, and chose to use deception to backdate it, then lied about it publicly. This makes their ethics no better than those that are attempting to profit from their work. That sort of behaviour does not deserve any kind of reward or promotion.
I think they first released 1.3 firmware under gpl v3 and then changed the license. thus not lying technically about 1.3 being open source when that happened. the license change was ca 24 hours ago, quoting slush from few days ago seems like a construction.
I'm not happy with the restrictions for future releases but as long as it is open source I'm fine with that.
They falsified their git repo to imply the change was made 6 months ago, then backtracked on that to say they made the change when it was actually made. That's lying, regretting the implausibility of the lie, then telling the truth without acknowledging the lie.
