I own original Sims 1 & Sims 2, why do I have to buy it again?

I’m not sure if it still works this way but, If you have them on disc (sims 2) you can message the support team saying your discs no longer run properly, then they may ask for a picture of a disc with the serial code and a handwritten message, and then give you the ultimate collection for free. I did this about 4/5 years ago though so they may not do this now they’ve released it for sale.
