Interesting comparison. It does seem similar in some ways. One way to view it is whether the license grants additional rights beyond default copyright law, or attempts to restrict rights. By default under copyright law, if a webpage serves you a video, you can do whatever you want for personal use, e.g. strip the ads out using software, save a copy for later backup, etc. The same is true for software, of course. The terms of use for these webpages try to get you to agree to waive some of these rights. Now by default, under copyright law, you don't have permission to re-sell or redistribute copies of the work, and there are limits on derivative works you can make. Most open-source licenses grant you additional rights which normally would be restricted by default. The licenses say, you have permission to do some of these things under some circumstances. But they usually don't try to to take away rights you already have, e.g. "you may not store this code on any solid state drives or modify it in any way for personal use to include the letter Q".
