Open source software has specifically devoted much of its efforts to ensuring it never breaches those copyrights.
They might look at Oracle SQL DB and say “Damn, that looks so useful and well-written. Well, I guess we could copy its codebase and pretend we wrote it ourselves…but it’s probably safer to re-implement it from scratch.” Then you get alternatives like MySQL.
That’s a fast example that probably ignores extended history of database wars, but you get the idea.
