In a considerable amount of cases, the ISP's customer is also the spammer. I would prefer not to talk to them when 
complaining about their behavior - in the best case, they will ignore me, in the worst case, they might do something in 
revenge.

The IP owner is the one who can pull the plug on misbehaving customers. As it is much easier to identify IP owners, I 
can collect reputation data about who I can trust to handle my abuse complaint responsibly, who will just ignore it, who 
will forward it unedited to their customer. Depending on this assessment of their trustworthiness, I will or won't report.

There are very few cases where reporting to end users makes much sense. Either they operate their system responsibly 
including monitoring the mail rejects and bounces, then they already know there's something that needs to be fixed, or 
they don't, and most often don't care, and my complaint will probably not change that.

Cheers,
