Debian gives attribution to every single open source project in existence that is capable of running on Linux, and is Free Software. It is exactly the project that shouldn't worry about copyright.

The "moral" argument I haven't even heard. It's just people pouring out invective, likely imo because Ruby-monkey is not going to be a $150K job anymore. I have problems with these companies, but companies who are problematic can be targeted specifically, and somehow everybody started using Facebook's frontend framework and Microsoft's IDE, all on MacBooks, and this is what they're throwing a shitfit about. To me it's narcissism, not a coherent moral objection.

If you hate these companies (as you should), there are open models. But most didn't object to anything that didn't threaten their income.
