Earlier quoted context omitted.
To be fair, Blackberry (RIM) was not bigger than Apple on the day of the iPhone announcement. Also, RIM was kind of forced to build something like the iPhone by Verizon according to Losing the Signal by Jacquie McNish https://smile.amazon.com/Losing-Signal-Extraordinary-Spectac...
To be honest, there is some truth in the ideas behind the point though. RIM always liked to control everything, and at most give Enterprises control, but not end users. Apple targeted consumers, and relied on consumers to push into enterprise for them. IIRC, it was actually some time before iOS even supported basic enterprise features (like company control and reset for company devices, etc).
RIM knew who their market was, and frankly should have been fine if there hadn't been a hype panic. Heck, their top market cap was a year after the iPhone.
I cannot help but think of a world where there was an actual "consumer" Blackberry device. I think the Bold form factor with the Passport keyboard UI and advances would have been a pretty nice machine. It was even thick enough for a really good camera and battery. I can even see the shooting video commercial tag line "Live Life in Widescreen" with snark about vertical video.
