That open letter is dated 2010. Flash was dead-man-walking for years before that insofar as new development was concerned. I was there.
I would propose that any serious web app development team grouped Flash on the client in the same "basket of deplorables" as the JRE, ActiveX and Silverlight long before 2010. Just a headache waiting to cause you compatibility support calls. Client plugins were to be avoided at all costs if possible.
I agree with other comments that Apple was killing flash only in the sense of putting it out of its misery - like a bullet for lame horse - and only waited as long as it did for compatibility reasons.
