My understanding is that gogo was the main limiting factor. That technology just didn’t support the bandwidth necessary to have functional free Wi-Fi. They didn’t want to start the process until they had enough of the fleet converted to viasat so that customers wouldn’t have the Wi-Fi on half their flights become essentially unusable. My experience with the viasat since they turned on the trial has been somewhat limited, but I haven’t noticed any issues yet. Nothing like the RJ gogo which is basically useless.
