Would you be ok if the screen got worse?
Or if the newer machine was noticeably heavier?
What if it had half the battery life of the predecessor?
With respect, your line of thinking and argumentation here is non-sensical.
I would defend Apple's right to make such a machine, yes.
Apple should have the freedom to make any kind of machine they want. The only exception should be machines which is dangerous to use or interfere with others (like using electromagnetic frequencies wrongly).
I would also defend your right to buy such a machine. Or not to buy it.
