Wow, I had no idea this existed. I built a similar thing for my own personal use for my local airport (Minneapolis/MSP). I looked at using an Amazon Dash button, but the lifespan is not great and the convenience is not high. Instead, I use SMS via Twilio and their cloud functions (source:

It's pretty handy to be able to say to my watch "Hey Siri, text complain to Dan Boivin" to make a complaint. (Dan Boivin is the chair of the Minneapolis Airport Commission, who I have entered into my contacts).
For those griping about people buying homes after airports existed, there are a couple things to defray that argument. Yes, the airports existed, but the traffic at airports have increased. Airlines are flying more smaller regional jets, which means the frequency of flights have increased. The FAA recently changed flight patterns (part of NextGen) that resulted in some areas seeing much more air traffic than they had in the past. And, airlines are not doing the steep takeoffs like they used to in an effort to conserve fuel, putting planes closer to the ground for longer, resulting in more noise.
