Boy if that doesn't ring true. Kudos to PuTTY's author for making it so easy and low cost to do the right thing that those profit-seeking automatons we call "companies" actually will.
The same logic applies to other concerns like accessibility, which is one reason why I'm making one of my contributions in that area [1] available as permissively licensed open source. It helps that my current funding source for that project also wants it to be open source.
