Yeah, but this is the size of a USB stick, with that comes the expectation/assumption that there is no power cord.

Really funny. Everybody else does it. Even though two devices are not comparable in form factor. Why it is in minuscule fine print though? Please ...

Really not a problem.. The power cord is only required on certain HDMI ports.. and it likely won't be needed on future/modern HDMI ports.

Why is this even an issue?

"Everyone else does it" has never been a reason, only an excuse.

This isn't even the same as devices that always require AC power but don't show a cord. It's basically a method of providing backwards-compatibility with HDMI ports that don't provide power, but if you're using the state-of-the-art TVs they show the product with, there's no power cord necessary.
