Intel doesn’t sell fab services, so it’s not an issue. However if you offer and advertise a service at a listed price (as SpaceX does), you can’t always refuse to provide that service to specific potential clients just because it serves your commercial interests. It very much depends on the specifics of the service and market competitive situation.
This is factually incorrect. Intel has in the past and is currently trying to sell and expand their foundry services. They just happen to have done a horrible job of it so far and have repeatedly lost foundry customers (like Achronix) as a result.
