It depends on your perspective surely? As a lawyer your job is typically to protect your client from legal risk, so if users are happy to sign a really expansive set of terms (which experience shows is the case) that gives grants lots of permission to do stuff with their data then that's low risk. If you as a business don't want that then you need to make it explicit that you're willing to take on some extra risk.
Also by using “standard boilerplate” they are using language with meanings well established by precedent. Craft your own version in “regular English” and it’s much more open to litigation.
