It's not reasonable to presume that any specific thing is the best solution for the "vast majority". A healthy ecosystem arises when lots of people with different use cases and preferences build the optimal solutions for themselves; when people try to build universal solutions based on speculation about what's optimal for "the vast majority", that's when things start to go off the rails.
