The words "not overwhelmingly antagonistic" are an interesting choice for a report that cheerfully concludes that "when given a choice between a normal music CD and a 'copy-once' CD priced $5 less, 33% of those who do not rip CDs and 27% who rip CDs preferred the copy-once CDs." So, to keep in the crude phrasing, two thirds of the (CD) users do not prefer a 'copy-once' CD, even at a lower price...Link (via Copyfight)
The distinction between rippers and non-rippers is interesting, if one takes it as a difference between users who do and do not make active fair uses (presumed that the do's keep from (subsequent) infringing uses). With a margin of 6% it seems that even the people that do not copy CDs (yet), are not so eager to hand over this possible (fair) use. I would say that there is an awareness with (these) users that copy-protection is not something to buy into under the current conditions. And I'd say that a median of 70% saying "No" could qualify as "antagonistic", overwhelmingly or not.
