Bin patching won't get you DMCA'd, and it's really not so different than writing a shim nowadays. Tooling has come a long way.
Doom is a closed source game that was finished, polished, and then open sourced. Strange to use that as a FOSS example.
The FOSS-from-the-start examples would be Tux Racer, 0ad, and so on.

And yet, here we are running Doom on our toasters, refrigerators and watches.
Summarizing, closed source projects die. At best you can run them in an elaborate museum (emulator) and at worse, you can attempt to Frankenstein's monster them by injecting DLLs.
Open source will outlive us all.
How many places does Doom run?
