I don't interpret "substantial" here as affecting the 'de minimis' requirement for infringement, as that would require other language. I'm pretty sure every court will instead interpret the word "substantial" in the MIT license as referring to the concept of "substantial similarity", which must be demonstrated in any copyright infringement case - https://en.wikipedia.org/wiki/Substantial_similarity https://en.wikipedia.org/wiki/Substantial_similarity I distribute software under the MIT. "Basically no strings" != "no strings". I expect attribution for any derived program which has substantial similarity to my software. I regard the presence of the word 'substantial' to indicate that the license applies to even modified forms of the software. As that Wikipedia link points out: > Under the doctrine of substantial similarity, a work can be found to infringe copyright even if the wording of text has been changed or visual or audible elements are altered
