Yes and for a while it wasn't allowed at IBM either for the same reasons. The latest changes made it possible again which is why now they can/do use it. Source

  This is absolutely correct. Before the end of last year, getting approval to use it was a very challenging process. However, many teams went through the process in order to use it because of how valuable they believe React is to their products. Groups like IBM Watson IoT were fortunate enough to get portfolio-level clearances as well during that time. Thankfully the process changed and many product teams add React to their list of libraries/frameworks to evaluate for their use-cases.
