Couldn't not comment on this one. AS is around the corner in the living room currently on his PS4. My personal view is I hate the thing, as it has become a particular cause of much rancour in our household. AS doesn't seem to be able to moderate his use, nor be very calm when the games aren't going his way. However, it seems to be the main way that AS interacts with his peers and he would feel very left out if he didn't have it.
We put on firm time restrictions, but he absolutely hates this. Perhaps the most perturbing thing is that there are many parents who do not seem to monitor their kids use whatsoever, and AS has reported that there are kids who were last on in the early hours and indeed children who come home on a Friday in their school uniform and when he has seen them on the Saturday they have neither changed their clothes nor managed to go upstairs to bed. So hard to impose sensible limits when AS is surrounded with this. Yes, we can be the worst parents in the world for actually having some boundaries!
Sounds like your son was really venting his frustration, but I'm glad he has calmed down now. I wonder whether he is surrounded by peers who have less restrictions on their use of devices, it can't help. We have stuck to our guns on the time limits, but haven't ever removed it, as I know that it will be melt-down territory. Interestingly, when we have complained about the level of noise (angry) associated with the use of PS4 (and it can be bad!), AS has volunteered to take it back to the shop himself. I don't follow through on that as I know it is really that he is trying to "punish" himself (a long-standing thing that isn't particularly healthy or good for his self-esteem).
Sorry, I've rambled a bit here. I hope there is something of use in this post.
