Forever Free Packs for Everyone
The Sims 4 is a 10-year-old game with over 90 DLC packs, and EA will likely keep releasing more for years. Competing life-sim games like Inzoi and Paralives offers much of this content in their base game. For example, Inzoi can provide content equivalent to 60–70 Sims 4 packs in its basegame for the price of just one expansion pack(40$) and we already have 17 of them.
To stay competitive and keep players engaged, EA should make some older packs permanently free—such as Seasons, Cats & Dogs and Get to Work. Giving 2–4 free packs from each pack category would greatly benefit new players so they can complete other packs without pirating.
For players who already own these packs, EA could offer new Kits free for a month (like they did with Desert Luxe Kit when The Sims 4 became free).
I think forever free packs should be;
2 expansion packs -> seasons, cats and dogs
2 game packs -> dine out, get to work
4 stuff packs -> cool kitchen, bowling night, backyard, spooky
