Thanks for your comment!
I think you’re right that some corporations do name organizations in their press releases, and it seems more likely that groups will be named if they are using a more collaborative approach. For what it’s worth, in the paragraph you quoted, I now think that I anchored too heavily on my impression that groups such as THL, Mercy For Animals, and Animal Equality are quite rarely (if ever) named in the news or press releases associated with the welfare policy statements, or in the welfare policy statements themselves. As the majority of the organizations we evaluate usually use a less collaborative approach, I think the paragraph you quote will usually hold for the groups that we evaluate.
Still, even in those cases, I think that you’re also right and there should often still be some indirect evidence available from the timeline. That is, evidence of an organization campaigning at t1 and then, usually a short time later, at t2 evidence of a corporation making a commitment to the related welfare standards. For particularly important commitments we do look at this evidence but for the majority of commitments we don’t.
I think that your comment helps provide some important nuance to this discussion and I have left a link to this comment in the piece itself. Thank you again for the comment!
