> Sorry if this sounds overly critical but I find it inethical to use the Chinese clones of Apple products.

Unlike most, not everyone is inclined to pay for the privilege of closed source, proprietary walled gardens (like those from Apple). People, especially those who believe in open source and free software ideals, consider the above practice unethical, which is probably why they don't buy Chinese made Apple laptops. Those users are largely in favor of sharing technological innovations for the benefit of everyone, instead of guarding them for a select few. So, no it is not unethical because, in the end, it doesn't harm the end user.
