"I can't believe the level of ignorance of copyright laws that sometimes floats around."

Well, not everyone is well-versed in the complex and sometimes confusing matters of copyright ... there appear to be some grey areas about what the grey areas are. :-) The DMCA for example is recent enough that court precedent hasn't been established for all possible scenarios, so I can appreciate that some of the ignorance and confusion is understandable. What gets me is the presumed authority with which so many people put forth things that just aren't true. If you're speculating, indicate thusly. If you aren't absolutely sure, don't pretend that you are. Pretty simple guidelines for saving face and avoiding the spread of potentially dangerous misinformation.
