I'm a little confused, I thought Thread was exclusively based on open standards, like 6LowPAN, that already existed before Thread. How can a licence be required for those? I understand the application layer Matter is new (although also using open standards like CoAP) and might not be that open.

Thread adds mesh networking on top of 6LowPAN. Thread, and Zigbee and ZWave, don’t have range to cover whole house so need relays and added mesh.
