I pretty much 'learned' to deal with the shitiness of the Pro Controller's D-Pad after playing all day, yesterday.
In the end I was nailing air Hadoken and Raging Demon with Akuma without issues most of the time. But yeah, Pro Controller D-Pad is shit.
I am not seeing these issues. Maybe you should contact nintendo for a replacement? It seems like people are calling the pro controller dpad shit because they read it on the internet.
Like I said if you press the button only when you want to be pressing the button there's no issue. If you mash your thumb all over the pad you are going to get the random inputs.
