This may be the case.    I support research,  BUT  using  solely methods
that do not involve  generating BGP announcements for aggregates   or
otherwise taking actions that might redirect any traffic covering address

those organizations.

Announcement of a broad covering route can cause unwanted traffic
Occassionally NSPs internally  use broad covering routes of their own,  and
 broad improper announcements can interfere with this.  Most popular is the
/0 route (default).

I would say it is appropriate for ARIN to support the network research.
