Just like Apple can design their product in any way they want, all these hackers and programmers and creative business types can complain all they want. But because they complain, does not mean they want to get into hardware business.
So just like the advice "if you do not like the devices, buy something else" is valid, so is "if you do not like hearing critique, grow a thicker skin".
We are (mostly) from free countries, with freedom of expression and all that jazz.
