I like "Hi Team". I do use that in certain social circles, but I do get the point of the article.
Survivor, the US TV show, used to say "Come on in guys" until recently where they made a point to discuss the topic on camera with the contestants. There was a variety of opinions, but they ultimately settled on "Come on in." which conveys the point in a neutral tone.
"Team" makes sense when addressing... well, your team, like if you're in a huddle of basketball players. But there are many contexts where it doesn't make sense as a general purpose second person plural.
