The UK stopped capitalising every word in headlines back in the 1980s maybe earlier. It looks much nicer and is more readable. The bold tells you it is a geadline. US newspaper graphic design seems very retro to me.

The page title is “ChatGPT for teams”

I agree, but why didn't the original article do it? Or did they see the potential for confusion and deliberately not?

When a common word is a product / brand, how do you use that word in a title without bringing up associations with that product / brand?

Isn't the guidelines to submit the title as-is, no editorializing?
