Actually yes, to all of those questions. Making a campaign with the kind of production values that people expect out of a 2015 AAA title undeniably takes time and resources away from the multiplayer segment. Whether that loss comes to fruition in the form of less content or lowered overall quality, the multiplayer experience would without a doubt be worse to some degree.
I do not see any evidence that proves that this automatically takes away resources from multiplayer. They can increase team size. They can spend more time on development. To me Star Wars Battlefront is a very obvious example for a game which was created with limited resources (probably smaller team size/less time), and the result is a MP only game. If EA had invested more resources, they could have created an additional SP campaign.
