I think it can be phrased differently, though. A friendlier, more PR way.
"You acknowledge that simultaneous independent development of ideas frequently takes place, and agree not to sue us if something we publish looks like something you posted."
Obviously it would need to be cleaned up a little, but I think that's a more freidnly sentence and achieves the same goal.
