Those teams don't deserve such a high placing either.
The thing you have to keep in mind with CS:GO is that it's a bit of an old boys club. It's very difficult for an unknown org with unknown players to get into the top 30 even if they're better than some of the teams in the top 15-10. Similarly it's also very difficult for a big brand org with big brand players to get pushed out of the top 30, even when they underperform for months on end.
If CS:GO had a truly open circuit without invites, the top 30 would look VERY different right now.
