GoPro has a decade+ old ecosystem built around their products. Go to any mountain bike trail, kayaking spot, climbing location, hiking trail, and ask around if anyone has a GoPro mount you can borrow, or a waterproof case. If there's more than a handful of people the answer WILL be yes. They managed to become the de facto standard for sports videography simply by offering a stupid number of accessories that nobody else thought of or thought was necessary. While each new generation has changed and improved the most important thing is that what they've never done is get worse.

They haven't been displaced because it would take a company fully committed to matching GoPro accessory for accessory. THAT is where the real advantage they have is.
