If he's not "legally not in the right," why should I be helping him (doesn't that imply casting a judgement - that PadMapper is elevated above CraigsList because it's "the best apartment rental interface our there")?
What if the tables were turned and CraigsList was violating PadMapper's TOS? Would you be willing to help CraigsList (they serve more than only apartment listings)?
Should somebody be rewarded, even if (legally) not in the right, just because he/she is a hard worker/smarty pants/exemplifies the True Hacker Spirit?
I often wonder if there is some sort of unwritten clause that You-Must-Pull-For-The-Underdog to join Hacker News? (In the name of Divine Disruption, of course.)
