I’m a very much pro free software person and I used to think that GPL is basically the only possible option when it comes to benefits for free software (and not commercial use), but I’ve recently realised this question is actually much more ambiguous.
I think there are two sides to this issue:
- GPL forces all contributions to stay open-source which prevents commercialisation of FOSS projects, but also causes possible interference of corporate software design philosophy and all kinds of commercial decisions, if contributions come from companies.
- MIT-like permissive licenses, on the other hand, easily allow for making proprietary forks, which, however, separates commercial work from the rest of the project, therefore making the project more likely to stay free both of corporate influence and in general.
So it boils down to the fact, that in my opinion what makes free software free is not only the way it’s distributed but also the whole philosophy behind it: centralisation vs. decentralisation, passive consumer vs. co-developper role of the user etc. And this is where things start to be a bit controversial.
What do you think?
I can tell you about a project I was working on at a previous job.
There were open source kicad files for a thing we needed. We wanted to modify it slightly and then include it in our finished product and also offer it individually for tinkerers or as a replacement part. But they were licensed under GPL3.
Because of the license, instead of contributing some improvements to the existing prpject, our engineers were instructed to just look at it and learn from it and then do a completely new internal project from scratch. They were told to make sure it could not be detected as a derivative and never use the existing files. And then to include our planned improvements. Just so that we could avoid licensing it as GPL3 and were free to do it however we wanted.
So the end result is, a new proprietary thing got created, the company got money, the customers don’t get the source, the existing open source project got no contributions, even though it got exploited in a sense. There were other MIT licensed (and other licenses) projects where we have just contributed instead.
Don’t ask me why exactly the management/legal was so against GPL3. I’m not really into understanding it deeply, but my takeaway from this is similar to OP.
