Using the internet to its fullest? Lol that doesn't even mean anything. If you truly wanted that, go to the PC instead of the walled gardens of consoles where restrictions are the norm. As for arbitrarily... you don't know the meaning of the word. This is Sony's policy, they're not randomly restricting things. I want Sony to allow crossplay as much as the next guy, but this is just irrational ranting. There's nothing anti-consumer here. Sony didn't sell the PS4 as having crossplay. You weren't defrauded or mislead.
You aren't owed, as a PS4 owner, to demand how Sony runs its infrastructure anymore than you are owed the ability to order a Big Mac at Wendy's.
Yes, the Internet is built on a set of protocols that are well understood and have been operating for many, many years now. The internet is not Sony's infrastructure lol. And, yes, the policy is arbitrary when it is imposing a restriction on what is otherwise an open and interconnected system.
Your analogies are horrible as well. Feeling obligated to order a Big Mac at Wendys would be analogous to feeling obligated to play Sea of Thieves on PS4. Nobody here is arguing that companies should be forced to release their games on other platforms.
I am, however, free to order a Big Mac from McDonalds, and invite my friend who has just ordered a Dave's Classic from Wendy's to come sit down with me and McDonalds, and we can both eat our sandwiches together, right there in the McDonalds. Imagine if the manager of said McDonalds stopped said friend at the door and refused to let us eat together just because he bought his sandwich somewhere else? THAT is just as ridiculous and arbitrary a restriction as not allowing crossplay once the developer has done the work.
