Someone == a PR firm: http://www.eileenkoch.com/ (warning: noisy) but as the current revision reflects, Wikipedia articles are built with respect to due weight and neutrality. While it's not ok to hide unflattering info, it's also not ok to bloat a short encyclopaedic article with court case details with the intention of highlighting how bad a guy the subject is.

While in the real world, Wikipedia articles either hide unflattering info or act as smears depending mostly on which faction manages to edit-camp that article more effectively. Regardless of what is "ok"

That's a silly caricature of how the place works, and not something I've experienced in the 8 years I've had an account there.

In addition to PR efforts, there are also some experienced non-PR Wikipedia users who take a slash-and-burn approach to content that's not fully compliant with Wikipedia policies. Rather than attempt to pare it down to what survives, they will simply remove it all.
