EdX reserves the right to modify these TOS at any time without advance notice
My interest was spiked. It continues:
Any changes to these TOS will be effective immediately upon posting on this page, with an updated effective date. By accessing the Site after any changes have been made, you signify your agreement on a prospective basis to the modified TOS and all of the changes
Aha! Not only do I have to give a carte blanche to whatever they feel like to write in there in the future without telling me, but also after reading the new terms, I already accepted them as I had to access the site to find out about them. Catch 22.
Another glance a bit further down the page, I noticed I had to grant edX a license. Interesting I thought, let’s find out. Anyone remember the hot water Facebook found itself in a while back?
License Grant to edX. By submitting or distributing your User Postings, you hereby grant to edX a worldwide, non-exclusive, transferable, assignable, sub licensable, fully paid-up, royalty-free, perpetual, irrevocable right and license to host, transfer, display, perform, reproduce, modify, distribute, re-distribute, relicense and otherwise use, make available and exploit your User Postings, in whole or in part, in any form and in any media formats and through any media channels (now known or hereafter developed).
Clearly, that’s a lot broader than what’s needed for the operation of the site where users’ comments are shared between other users and instructors.
