Because people want strong typing, but also want other things. It's possible to want multiple things, and bemoan that whwat you use is still missing things you want.
Concretely, Django is way more usable than basically any web framework from the "strongly typed" space, especially for "dumb" CRUD stuff. And you're not hit with making decisions about how to do a bunch of things (though you can swap out mostly any part of Django for something else if you want to).
