A frequent criticism of end-user licensing agreements is that they are often far too long for users to have time to read them in depth. As of March 2012, the end-user PayPal license agreement was 36,275 words and by May 2011, the iTunes agreement was 56 pages long.  The message sources that reported these results stated that the vast majority of users do not read documents because of their length. A lease gives the tenant rights to the property, while a license is just an agreement with the owner for the use of the space. This means that a tenant has certain rights and a higher guarantee under a lease agreement than a licensed licensee. Unlike ITAs, open source software licenses do not function as a contractual extension of existing legislation. No agreement is ever reached between the parties, as a copyright license is simply a statement of permission for something that would otherwise not be allowed by default by copyright.  Several companies have parodied this belief that users do not read end-user licensing agreements by adding unusual clauses, knowing that few users will ever read them. Aprilscherz added a clause according to which users who placed an order on April 1, 2010 agreed to irrevocably give their soul to the company, which 7500 users accepted.
