Rather than remove those apps they would make it harder to put them in there in the first place. they'd have to go through a QA process on the market's end instead of the developer. While there is a lot of crap out there the nature of the web is someone out there has tried every single app most likely. If one of them let your phone squeeze oranges into juice we'd hear about it pretty quick and download that "must have" app. That keeps the market open to all. Less control always means you'll get the extras in there.
