It could be due in part to what EA stated (then removed) also about the PS4 1.50 update: According to Electronic Arts (via help.ea.com/article/sony-playstation-4-update-1-5-instability), the PS4's 1.50 firmware can cause a PS4 to malfunction.
To quote: "Sony has released a firmware update for the PlayStation 4 that is required for many features on the console. However, this update also results in stability issues while playing games on the system.
This affects all games on the PS4, including EA titles, causing crashing/freezing and non-responsive connections between the player's console and their TV Screen.
Unfortunately since it's an issue with Sony's firmware, it requires a new update to fix it. Sony is working to resolve the issue as quickly as they can. They will update their System Update page as new versions are made available, and we will keep this page updated as we find out more."
