I don't agree with dropping the services even though I don't use it.
People may have given tv's the nod for this feature when they were buying which would suck to have support pulled.
The vita also, I recently found the joy of remote play and could see myself using now if I didn't own my older consoles.
But that a side, I think it's safe to assume that the information they have shows mostly ps4s and PCs using the service to the point that they may be saving more keep maintenance on only those 2.
