I felt like the arguments behind my opinion were implicit.
Consistently not showing bias makes for trustworthy lists. Nobody (well, nobody reasonable I'd argue) will trust an IP blacklist from a major hosting company that actively excludes their own customers.
As for banning customers that get blacklisted, this does actually happen, especially on the more affordable cloud hosts that get plagued with massive scraper and bot loads. Anything from suspended, inaccessible servers that require manual intervention to network caps or CPU load caps. This is a rather extreme measure, but not one uncommon or even unacceptable depending on the exact IP blacklist you managed to trigger.
