What nonsense. Governments restrict what people can or can't do with their houses and properties all of the time through zoning and other regulations. This can include safety standards, deed restrictions, occupancy restrictions, appearance standards, animal restrictions, business use restrictions, etc.
Just because the government may deprive me of income by not allowing me to open a fast food restaurant at my house, convert it to a multifamily rental, a hotel, etc. etc. etc. does not mean it's not my property.
Stop with your nonsense. Apple owns iOS, the App Store, iPhone etc. and related IP, patents, design rights, branding, etc. Once again, it is not nationalization of private assets and Apple can still make a lot of money from iPhone/iOS, the App Store, etc. through CTF and/or App Store fees/commissions and/or the sale of iPhone/iOS, can choose to shut things down, sell them, etc.
