While it is probably hard to understand, the other poster's interpretation is legit as it is referencing an acknowledgement of rights. Without such language, you could provide your voice to this and then when they release, you could say "hang on, I never agreed to give you permission to release this to the public, use for your own purposes, etc." As far as "may" vs "should"/"will", that'd be very unlikely for them to put into the terms: what happens if they decide tomorrow to abandon the project and just leverage a different data set? They'd now be beholden to release something.
