I think it goes beyond the sims though. Just about all games today have numerous ways to make these companies money outside of the cost of the base game. That will never change. They barely make a game bug free before releasing... so many games have day 1 patches all ready to go. It was never like that until players accepted it. Just like DLC... loot boxes... in game money... etc.
So I don't see this changing for any game made by any company. It's only going to get worse.
As big of a money grab people feel these packs are with the Sims, EA pales in comparison to Rockstar and some of the others.
Even if no one bought this pet stuff pack, EA will not abandon their strategy.
But I can't say I blame them. Their only goal is to make money. When a game is popular, they are going to come up with a plan that allows them to continue to make money from whatever product they are selling. They gotta pay their employees who work to develop their games/apps/DLC whatever. That money has to come from somewhere.
