I am aware, the question was rather how large of a problem it is as compared to for example PC. Most modern consoles do not have emulators. Exception now being the switch. Since consoles the last few generations have required hardware modding or specific (generally early) firmware that you cannot downgrade to.

It doesn't feel like piracy on the actual consoles is that large these days since most people wont go through all that effort.

So the question was not if it exists, it does and most likely always will in one way or another. But how large of an issue is it? How many of active users do have modded consoles or engage in piracy on their consoles? It's not like on PC where its generally pretty effortless to accomplish, a console requires at least some form of dedication or a wallet to open. And I just don't see that as a large issue.
As for the anti-cheat part, how much of an issue is cheating on consoles?
I'll break my thoughts down into a few points by number regarding the quoted post.

Thing is, there may not be emulators for current consoles.... Yet but I can promise you that's being worked on and they will appear one day.
The day they appear being the variable no one really knows and Sony along with others aren't taking any chances of when that may be. If it's really early in the life cycle of the console, it's a no-brainer whats gonna happen next and what effect it will have towards Sony and game developers.
I've seen recently PS3 games still for sale in a few stores like Wal-Mart and even bought one of them because I have a PS3. Since PS4 is still largely relevant for game sales, that plays a part to what these hackers/pirates may target.
Can't guarantee that but it is a possibility.

As for how many are trying to crack games and consoles well, all it takes is just one to do it and it's on.
If memory serves it was the PS3 that a single hacker managed to make a big breakthrough with concerning the console firmware and things snowballed from there. Others picked up on what this one guy had done, then other things happened as you might expect.
However I don't believe the PS3 has been 100% cracked but I also woudn't doubt it being cracked all the way either, esp by now with that console gen being as old as it is.

Related to dedication, you know like I do a few would love nothing better than to outdo Sony just because they are Sony.
It's more of the challenge aspect that plays into it and yes, again there are a few that just don't give a crap and will go for it just to make a point. Maybe Sony pissed them off at some point and all they want is to "Show" Sony what the deal is regardless of any investment involved or whatever else.
They are out there... Somewhere and we all know it.
That's what I'm thinking and based on things I've seen over my 30+ years of console gaming I do believe all that could be the case, at least in part.
