Yes then tell me about the many forms of slavery. How things become norm and appealing to the slave. Over time the slave would even defend that paradigm. Also you think slavery is more psychical then mental?

If you chose to allow yourself to be a slave of Apple then that's your choice, there's plenty of options out there, no one is forcing you to buy an iPhone.

Using that logic you can say everything is slavery since we are slaves to certain foods, entertainment, sex etc...

Calling it slavery is just a cop out for your own weakness you're looking for someone or something to blame. Kinda like people calling drug addiction a sickness, no one put that needed in your vein.
