Otherwise you would have seen a lot more lawsuits related to Bitcoin. A simple one would be early developers who thought their contributions should be paid after projects took off that are secondary to their work. Or even trying to enforce FOSS, but killing projects along the way that would have been helpful to the community. (Of course they deserve compensation, but if they do not like the MIT license then they can develop on different projects. Bitcoin is a currency intended to be much broader than any individual.)
I want to point out that this lawsuit mania is going on right now against companies using [L]GPL v2/3 software which did not make any link to the GPL'ed module available. It's because [L]GPL requires not only attribution but also a link to download that particular code in order to use it. So it can be seen a bit why Satoshi wanted to avoid that kind of early torpedo to Bitcoin.
