Nah, people using Yahoo are still using it today. What happened was the growth of new users of the Internet in general was so massive, T+1 cohort’s early adopters outnumbered T cohort’s majority. the better product won, it’s just that the friction of switching didn’t matter. Switchers didn’t matter.
On one hand, true, my mom still uses Yahoo. But email has a strong network effect - you need to update everyone & every service who has your @yahoo address. Switching does happen there are no network effects. Nobody uses Mapquest or Ask Jeeves.
