In the past it was much easier to attribute a website to a single person or a small group of people, and maybe they were able to publish contact details like email addresses without fear of them being harvested and spammed. Websites didn't really have comments sections so often so the reliable method for feedback was email. Maybe email was also a lot less tedious back then - it strikes me that these days the main purposes of email accounts are to allow registration with other online services and to hold the huge amount of spam that usually happens as a result of registering for online services. I don't know many people my age (Gen-Y) who would even dream of using their personal email accounts to actually communicate with actual people outside of places where it is strictly required (like applying for jobs), even less so their friends. They're too used to services run by corporate giants (like FAANG) and are being trained to interact in very specific ways, e.g. in direct messages in apps, in the comments sections or through "Like" and "reactions" buttons.
