DragonWriter, you might want to know the person you are talking to is Boris Zbarsky - a lead Mozilla developer for over a decade, member of multiple W3C working groups and generally one of the smartest and most respected figures in the industry. So yeah, I do think you can trust him:)
Yes, because they believe it is not in people's best interest. All the common problems caused by rapid release schedule are being worked on and will be fixed very soon - silent updates, add-ons compatible by default etc. Disgusting? Chill out.
The point was not whether they make profit but whether their decisions are motivated by profit - they aren't. Mozilla Corporation must not put financial profit above the mission stated in the Foundation's statute.
Perhaps you should take your own advice and look it up? Mozilla is a public benefit foundation first. Mozilla Corporation is a wholly-owned subsidiary of Mozilla Foundation, and as such it must work for the Foundation's mission.
