My personal view on it is the same as yours, but I also think our personal views on whether someone else should claim ownership of their work doesn't really matter. Like you said, it takes an ungodly amount of work to put all this stuff together and yes, it's all readily available information, but that doesn't exactly cut down the time it takes to do it. If someone who's done the work doesn't want others using their data I think they should be afforded that respect, otherwise we might as well just say it's fair game on everything because there's no functional difference at all.
