It's more or less the same really - people are forced to check-in or else they'll lose access to the games they paid for. Because that's what the higher tier PS+ is for, and if you don't need the check-in for the base tier, why is it mandatory for the higher ones? Doesn't make any sense other than Sony wanting people to re-purchase the games they might accidentally lose access to.
Gaf often complains how the industry has gone shit, about greedy publishers and what's not, but it's happening only because whenever something like this happens people are eager to justify or even defend it. And as always it only gets worse and worse, step by step. First it was paid online, then price raises, now online check-ins, no wonder console gaming is such a shamble, but hey, maybe that's exactly what the console crowd deserves, being fucked in the ass over and over again, because clearly they enjoy it.
Sure you do have access to the internet, but really, will you go like "sorry guys, wait for me a sec because I have to login to PS+/XBL on my phone or else I'll lose the games I've been paying for in the past 2/3/4 years"? The fuck... If you're truly like this then you really have no life and gaming for you is to fill all the free time you have, so like I said, whoever defends it most likely doesn't leave home for more than just a few days tops.
This is so dumb honestly, I go on vacation exactly to forget about the every day live, all the surrounding tech, the society etc., especially if I'm on some tropic, sunny, exotic land, I want to enjoy that time with friends or family, not thinking about having to log in to some stupid console network. Plus, I'm most likely too drunk to even think about it lol.
Bottomline is, I can only imagine how the PC crowd reacted if Steam tried to pull something like that - log in once a week, month or whatever, or all you gaming library is gone. This is what separates Steam from what the consoles offer, where digital future is bad, it's the end of the world for some - it's bad only because you allow it to be bad, because you keep showing the publishers they can offer mediocre experience and services and screw you over.
