> Imho it would only be market failure if that freedom disappears

There is nothing inherently wrong with Facebook making React open-source. React undoubtedly benefits everyone.

However, the issue lies in the fact that this practice doesn't create a true "market". Facebook has made a relatively small and insignificant portion of their source code available for free, which doesn't impact their business significantly. Meanwhile, they have encouraged thousands of programmers around the world to develop React extensions and publish them for free under similar terms. For an individual programmer, unlike Facebook, this means giving away 100% of their work effort without charge. While this benefits society in terms of knowledge sharing, it almost always financially benefits businesses and big tech companies.

Overall, this model creates a situation where most programmers end up doing part of the job for businesses for free, and they have to earn their living by working for these companies as well.

This model exploits programmers' labor in two interconnected ways. Simultaneously, there is widespread public promotion that publishing under OSS licenses is moral and the only way to go.
