Like the saying goes, " It's not the plane, it's the pilot"
Let's be honest indeed! An experienced paddler? He flipped in a lake while leaning forward? That lowered his center of gravity, did it not? Lost his phone and soaked all his gear? Why wasn't the phone secured and the gear waterproofed? I think maybe he leaned to the side while talking on his phone and hadn't become familiar with both the canoe's primary and secondary stability. He panicked and swam. And he blamed the canoe for it.
I've never seen a canoe flip, tip or twitch, without a paddler in it.
Good judgment comes from experience, and a lot of that comes from bad judgment.
