&gt;Do you think it matters if Udemy is getting 50% of the revenue from the sale of pirated material? Do you think that changes their responsibility in comparison to a company like Youtube?<p>If Youtube still gets 45% of the ad revenue from content, then I suppose maybe that would mean Udemy should be 5% more responsible toward the original content creators than Youtube?<p>But it&#x27;s actually much messier.  If a song disappears from your Youtube playlist, well, you didn&#x27;t pay anything for it or really invest anything into it, so it&#x27;s just a minor annoyance.<p>But on a site like this, if you have paid to take an online course and have invested many hours in it when it suddenly disappears, that&#x27;s a much bigger annoyance.  You have a loss.  So they have a responsibility toward the &#x27;students&#x27; (customers) as well.  But that&#x27;s not all.  There are also the instructor accounts of people who may (potentially) make a living off of the courses they sell there.  If the site is too careless and quick about shutting down any course anytime anyone asks them to, then it could be spammed with bogus reports that would harm those people.<p>So they do need a solid process, with the legal paperwork, for infringement notification and counter notification.  Which they appear to have in the form of DMCA.  It&#x27;s not optimal, but it&#x27;s what we have now as a society in order to have a standard that doesn&#x27;t go too far in either direction without actual legal action.
