First, I agree it's cool that Atari, with all its ability to completely screw small projects over, didn't do that in this case.

But, at the same time, I find it interesting that "emulations and clones" are considered entitlement (in a derogatory sense), but copyright protection is not. Before 1976 in the US, the _maximum_ copyright term was 56 years, and that would require filing for an extension from the default of _only 28 years_.

I think it's easy to forget that copyright as we know it is not set in stone. Historically, after 28 years, most works became public domain and that meant you could do literally whatever you want with it and it would not be legally stealing at all. I think we as a society have forgotten what it means to have a public domain.
