I’m not sure. Toyota was famously anti CarPlay and Android Auto, until they reversed the decision a few years back.

I’ve not aware that they ever released a reason, but I was talking to a dealer slightly before this, when I had my 86 in for a fix due to a recall. He asked if I was looking a new model and I told him that CarPlay/Android Auto would a requirement for any new purchase. The dealership was well aware they were losing customers, and I’m sure pressure went up the line to the factory.
