You're missing the point entirely. It isn't about a comparison, it's about the user behavioral patterns, and there no reason to assume it will be any different this time.

The "average user", the vast majority of people whose choices in software and services directly influence the direction of the market, are on the whole too unwilling or too tech illiterate to use alternatives.

It's the tyranny of the default, and the primary engine behind the centralization of the internet: the average user complains but refuses to move if it would require even a modicum of adjustment or patience. They're drunk on convenience, and will drive a market off a cliff before they'll ever try something else. It's a pattern we've seen again and again and again, and there no reason it won't happen here.
