EA App Required Now?

At the end of the live stream the gurus stated that pc players can purchase Growing Together on EA app and mac user can purchase from Origin. I am a pc player and still play my Sims 4 through Origin. I don't want to ever switch over to the EA app, even though I know at some point in time I will be forced to switch. I'm just wondering, has that time come with Growing Together? I truly hope not. If so this would definitely delay my purchase of the pack. I also hope I am positing this in the correct category.
