I'm only half-joking when I say that one of the premier selling points of GPL over MIT in this day and age is that it explicitly deters these freeloading multibillion-dollar companies from depending on your software and making demands of your time.
On some of our projects this has been a great success. We have some strong outside contributors doing work on our project without us needing to pay them. In some cases, those contributors are from companies that are in direct competition with us.
On other projects we've open sourced, we've had people (including competitors) use, without anyone contributing back.
Guess which projects stay open source.
They never trigger the distribution clauses, and they own the copyrights of all the work being done. So if you NEVER distribute binaries outside your company's walls. The GPL is a giant nothing, for most practical cases.
That's why we're starting to see the AGPL more now. But even then, for INTERNAL applications. It's still a nothing.
The GPL doesn't cure people being greedy. It just changes how they are allowed to be greedy.
