Yes, admittedly, cantis probably aren't going to be the best for ultra hard-beasts doing thousands of miles at a time and sleeping in hedges, but different brakes for different needs and all that. Some people probably benefit from the simplicity of fixing it for the type of riding they do.
The idea that rim brakes (that served people well for decades) suddenly don't work because Shimano said so makes as much sense as saying riding bikes off road started with gravel in 2015.
