I really don't understand what you're trying to get at. I'm telling you what Basecamp works well for, and what I believe it was designed to do. You're telling me that you disagree with the marketing copy on their website. I didn't write that marketing copy, and I'm not interested in critiquing it.

Regardless of how your mental mapping of their marketing copy works, they've been completely explicit about the fact that Basecamp is not designed for people who want fine-grained schedule-based management. They've written extremely popular blog posts about why they think that kind of project management is evil. You can agree or disagree with that (I do both), but you can't tell them they have to add features they don't want to add just because you have a different definition of "project management".
