Because it is not the same result.

Yes, it is a similar result, but not the same. You give up a lot of control even using a smaller email service provider -- not the least of which is direct control of your own email data. Obviously, since it is email, there is nothing you can do about what others do with emails once they are received on their end, but it is still nice to have direct control of your side.

The counterpoint, however, remains valid. There is some work involved in maintaining your own mail server. If you use a provider, you don't have to deal with any of that -- it's always about tradeoffs. As the article says, however, maintaining your own mail server isn't as hard as a lot of people make it out to be. It takes a little of your time, but once you know the few things you need to do, I find it to not be a big deal at all.

Setting up offlineimap to backup your mail is easy. I run daily backups of my protonmail account so in the even they decide to do something nasty to my account, I wouldn't loose more than a day of mail.

True, and I use offlineimap for a different scenario where I do not have control of the mail server. However, it is still not the same level of control as managing the mail server yourself. I understand why some people don't want to do that, but again, I don't find it to be much trouble at all.
