Question - why does there seem to be so many different websites, which all seem to be part of medium.com?

Time after time I'll click a link to some article, realize I'm on Medium... but it's a different domain? Yet it looks exactly the same, and I'm already logged in?

Is is some kind of spam marketing, or a look-alike platform, or...?

Suppose you sell a B2B software, and you want to send emails to help the end user understand how to get the most of out it - how to ensure the right person is getting the emails?

Many companies will be using a purchasing dept or at least someone higher up will be paying. Does that mean they, instead of the end user, will be getting detailed instructions that they're not interested in?

I presume this issue is tackled in an existing neat and elegant manner? If so, could someone tell me what it is, as this is bugging me... :)
