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.
I get that, but I wonder if a company that does the practices that I mentioned would exist
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.
