Open source is constantly under attack from various corporate entities, so it makes sense that we should guard our image. Asking people to be clear about what is and isn't FOSS is a basic consequence of that. FSL is a source available license, and I am simply asking that its users make this fact clear instead of trying to associate themselves with FOSS. That is not unreasonable. That is not toxic. That is simply asking that people don't obfuscate the truth.
