Have I been pwned prompted me to abandon my old addresses and switch to a provider that allows trash mails and email aliases. Originally my address was breached by Dropbox and Kickstarter. It took me many months to switch over, as I did not have a complete list of all services I had registered with. So for many average people switching email adresses is often a very difficult task, so people keep them even in light of breaches. More important for the average user is to have a good password management system and know whether a certain password has been hacked.
