In response to issue: https://instantview.telegram.org/contest/astera.ru/template21/issue2/
I think both variants are possible.
"@ASTERA: Новости IT и финансов" is to what their wordpress site name is set. You can see that:
- looking related article iframe/widget (presented in article issue was created on and tons of others):
- looking at titles of pages with articles
- looking to what name is set at wp-api they expose: http://www.astera.ru/wp-json/
Difference from CNN is that CNN is proper noun, if you know what news is you probably heard of CNN. So it CNN case it's added short description (which is also obviously too long for title)
This site isn't popular by any means (articles struggle hitting 1k views) and because of that they have short slogan right in their name, so people who see it first time would have an idea about them.
As example Instant View IV has $site_name set to "Instant View Platform", while it seems like it should be "Instant View". That's done (IMO) because "Instant View" doesnt make any sense for someone who's never heard of it - and they use more verbose variant.
