Sure. So what? Even if you use Gmail, you should do it behind your own domain. So that you are not locked in. Now I can understand saying "I have been on Gmail for years and I can't be arsed to update my address everywhere". It's not a lot of work (I've done it and it was actually a lot easier than I had anticipated), but it's work. And in a world where people can't be arsed to spend 3 clicks installing Signal, updating an email address sounds like a PhD. (I am being judgemental here, but you get my point :-) ). But the article says "I am moving, I decided to do the work of updating my address everywhere!". And the only reasonable way to do this is to move to your own domain, IMO.
