Social network Facebook has caved in and will relicense some of its popular open source projects without a controversial anti-patent troll clause, following an outcry from the developer community.

The controversy was triggered by Facebook when it added a clause to the open-source React Javascript library that’s used to build Web application front-ends.

Intended to protect Facebook against patent trolls, the clause meant developers would lose the right to use React if they asserted any intellectual property rights.
