But still, I have this feeling that many people who would be competent to own their domain just don't do it. And they could give an email to their family, too. And help friends setup theirs.
I'm not completely sure that the issue is "it's too hard". To me, it's like password managers. Sure, it's too hard for some people. But most people just can't be arsed to use a password manager, though they would be totally competent.
"It's too hard" is, in my experience, often an excuse to be lazy.
For most people, if they want or need to switch email providers they will simply sign up for a new service, give people their new address, and move on with their life.
This whole conversation is a lot to do about something that the average joe just doesn't give a shit about. It isn't laziness. It really isn't that important of a life task for most. It's an appropriate prioritization of tasks under a lifestyle different than yours.
I don't really see an actual problem here, unlike some others commenting, but it is a general shame to me that more people don't have their own email domain. It would make the world more... colorful... somehow, even if in just a small way.
I honestly think that most people don't know why it matters. 20 years ago I was happy (and proud) to have gmail, and didn't see a point in having my domain. Until I chose to move away from gmail, and then it all made sense.
I have an example: many (most?) universities give you an alumni email when you graduate. Some offer actual hosting, but others just ask you to redirect. It is free, and for many universities, graduates would trust their university more than gmail, right? And it wouldn't lock them into gmail. Still, none of my friends from university use it. Most use gmail instead.
Now tell them: "Look, if you use gmail, then Google can read all your emails. You didn't give a shit 4 months ago ("I have nothing to hide"), but now you've heard of random Canadians and Europeans getting deported or declined entry in the US for random reasons, including one who wrote stuff against Trump. How do you feel about the US reading you emails and deciding whether they should deport you or not based on that? If you controlled a domain, you could move away from gmail. Now you can't. Also know that if they can read your emails, it means that they know the flights/hotels/trips you booked, whatever you bought online, and they can just access all your accounts everywhere."
What will they think? "If I was to do it again, I would still use gmail" or "Would actually be nicer if I had been using my alumnus email all along"?
This doesn't happen because people are using gmail. It happens when people post things on social media or get searched at border crossings.
I'm not following.
That was my point, I'm happy to see that we agree :-).
