I don't think anyone is crying about Bixby. I think there may be one or two crying about Bixby posts.
I don't think anyone cares about Bixby to hate it... Everyone that buys a phone will press the button, maybe give it a shot, and if they don't like it just ignore it.
The issue people are giving their 2 cents on, or complaining about... is that you can't disable it if you don't like it. You couldn't even disable the button if you don't like it. You can't even disable the swipe left that take you to the Bixby cards.
At least with the S6 I played with you had Flipboard installed and had a swipe left installed to go into the flipboard widget... but you at least had the option to disable it by Samsung.
And when the devs find a way to disable the button, Samsung takes a heavy hand to block it. I do find it find it stupid you have a dedicated button that you can't do anything about and in a position that you WILL hit now and then.
I think it's not unusual for people to discuss it and even be annoyed with it. Hopefully it keeps getting discussed so that devs are more determined to find another work around and give Samsung the finger for blocking it. Why tell people to stop talking about it... just lay down and accept it? lol.
