Yea, the multiple uses of a single account strikes me as the bigger issue here. Why would my email access by tied to my ability to comment on a video sharing website? Same issue as Oculus requiring a facebook account.
I disagree, it’s the tying of your email address to a provider. If your email goes to “first@lastname.com”, then a quick MX change side steps a Google ban trivially.
But if your email address is “name@provider.com”, you’re kind of screwed.
Now the problem is making the acquisition, setup and maintenance of personal domain names and mapping to an email account something the average literate adult can manage.
…and chuckling ruefully as I recall walking recent college grads who are far better devs than I am through what needed to happen for SendGrid to actually work for one of their project, having to start with “what is an MX record?” and “where is that controlled?”
But if your email address is “name@provider.com”, you’re kind of screwed.
