PS4 cross platform

I have created this petition for gamers especially PS4 to allow us to play cross platform. Games like Rocket League, Minecraft, Ark Survival need to be cross platform. When we buy a game we agree to all these privacy settings and are ok with them. Sony’s excuse is because of players vulnerability but why can’t they add a clause to the privacy we already agree to. It is ridiculous to pay $60 plus dollars for a game and can’t play with all users of a game. Please sign this petition and let’s send it to Sony / PlayStation and hopefully resolve this ongoing issue.
