They don’t have to wipe out tile.
They've avoided selling their own HomeKit gear, they're licensing AirPlay to be put in TVs so people don't have to buy AppleTVs, and they stopped selling routers long ago. Even when it comes to dongles which everyone thinks Apple loves selling, they have a meager selection and have outsourced many of them (e.g. they don't have a first-party USB-C Ethernet dongle)
With the MFi Program, they still make lots of money on third-party products, without all of that costly R&D and support on their own end.
I was blown away when I plugged a full laptop USB C hub in to my iPad Air 4 and was able to use a USB keyboard, mouse and hdmi out.
