Apple doesn’t operate this way, and I don’t think many companies operate this way. Companies use the pieces that are valuable to them, and maintain existing contracts until those contracts are up for renewal. Then, they simply don’t renew the contracts.all while getting revenue from other companies for the old tech through the existing licensing.
I think with someone else said is more accurate. They wanted to do business, couldn’t get the terms they wanted, so naturally they ended the engagement. The company in charge now is effectively completely different. They very likely offered a deal that was much more favorable to Apple than the prior company did.but had to go back to the well and re-license
