EA does not own the Simpsons franchise. They had a licence deal with the owner, who was Fox but is now Disney. For whatever reason that deal is not being renewed.
If you rent an apartment and put money into paint etc, and the lease expires and is not renewed, you don't get your rent or investments back.
Everyone should know going into it that the game will eventually end. They all do.
I put money into the game, and got hours of fun out of it. No regrets. I'm not owed anything.
Exactly what Willy9292 said.
