Making access to a specific part of that code harder on purpose goes against the principles of Free Software.
Period. Money doesn't factor into this, value, contribution, they don't matter. FOSS is free to use, whether you contribute or not. FOSS is for everyone, "freeloaders", developers, anyone. That's the very point.
Yes, the code is still technically available with a bit more work in Stream's repos. That's not the issue. The "people are stealing from us" talk is the issue.
When a company that works in FOSS, and depends on it to operate, calls people using their GPL rights "freeloaders", you know they've lost the plot.
That's the problem. The value, the contribution, the development, the clone or not, the business: it DOESN'T MATTER.
