Note that there have been IP theft and other shadiness allegations from ex-members of the Apollo team.

If you do a little research you'll find out that there's plenty of "stay away" and "can't believe they haven't been sued into oblivion yet" indicators and all sorts of misleading claims and marketing.

My summary would be that it's a tightly-controlled, closed project lead by questionable people with well-documented histories of questionable practices including ignoring copyrights, distributing infringing software, deleting critical posts from their forums and putting out misleading information.
