This document discusses two common issues with platforms' terms of service regarding Creative Commons licensed content:
1. Platforms require a direct license for all uploaded content rather than respecting the CC license, granting the platform broad rights.
2. Platform terms impose additional restrictions that contradict what is allowed by the CC license, such as prohibiting downloads or commercial use.
It examines problems these issues cause both theoretically and practically, and considers ways platforms and CC licenses could address the problems, such as platforms explicitly acknowledging users' rights to reuse CC content or CC changing licenses. Other platform issues discussed are frequent terms changes, prioritizing their own licenses over public ones, limiting license options, and making attribution and access difficult.
