This could become an obstacle to adoption similar to what's been seen with Quviq QuickCheck: people who have Open Source projects need to publish (=distribute) test suites as well. Just as it's not very helpful to distribute test suites that require an expensive tool, people might be reluctant to publish PropEr-based tests if it requires them to convert to GPL.

Kostis did say that they would make an exception for OSS projects. I could not find any such exception when quickly scanning the repos.
