The "you knew it would be like this" argument (D3 related, but not only)

[artanis_neravar]

I've seen a lot of people, here and all over the internet, giving various justifications for why we should be ok with the D3 always-online thing, most of which were picked up and attacked by others (such as Jim Sterling and TotalBiscuit).
However, there is ONE argument no one ever attacks : the "you knew it'd be like this argument".
Now, the fact is, I knew about this for D3, and decided not to buy it because of it, but I cannot help but believe that SOME people will be buying D3 without having knowledge of it. I guess "needs an internet connexion" is written on the box, but that can mean a number of things nowdays.
My point is, just because we inform ourselves about upcoming game releases (well, I guess you do, at least a little, since you are on this website), doesn't mean everybody does.
In fact, I had this problem with Starcraft 2 WoL : I purposefully avoided any exposure to news related to this game, because I didn't want any spoilers, and ended up very shocked by the fact that I had to log in to play singleplayer.

Long story short : What's your take on the argument that gamers can't complain about certain features/problems in a game they bought because they knew this would happen when they paid for it ?

It is always the responsibility of the person buying a product to make sure they know everything they need to know before purchasing; You can't complain about buying a car and then having to pay for gas, so why should you be able to complain about an advertised feature in a video game?

The same idea applies for TOSs and EULAs, there is no case where you can sign a contract and then claim, "well I didn't read it" as an excuse as to why you have breached said contract, so why are gamers any different? What makes us so special that we don't have to abide by the same rules and practices that everyone else follows?

True, you expect someone who buys a car to implicitly agree to pay for the gas.
However, if you were to buy a car, only to have its engine explode five seconds later, you'd say you've just been scammed.
My main problem with TOSs and EULAs is that they are given for you to read during the installation. As in, after you've payed for the game. I find that to be dishonest.

Unless it was printed on the back of the car that it was going to explode after five seconds. And Diablo does say internet connect required, and if someone doesn't know what that means it is their responsibility to ask. Now if you bought it at Game Stop, saw the Requires Internet Connection and asked the guy behind the counter what it means, and he tells you that it only applies to multilayer, or you just need to be connected to authenticate the game, then you would be justified because then you did you due diligence and were blatantly lied to.

I will give you your point on the TOS though
