Apple does have a very anti-cooperative business practices that which goes against the spirit of cooperation of communism. Would a company like Apple event exist in a post-capitalist world?
By “a company like Apple”, I mean a company that it is extremely secretive, doesnt open source anything and doesnt cooperate with any other companies, and tries to make everything proprietary and have closed ecosystems.
No. The end of capitalism means the end of private property, thus the end of intellectual property, trade secrets, monopoly rent seeking, and treating workers like garbage.
