https://github.com/matrix-construct/construct/blob/0624b69246878da592d3f5c2c3737ad0b5ff6277/LICENSE The permission notice is similar to ISC, but says "is present in all copies" instead of "appear in all copies". I don't recognize the disclaimer (though that doesn't mean much) It seems you @jevolk added it in https://github.com/matrix-construct/construct/commit/676aaedbe805e03db5cf287889891758973f453e Can you tell me anything about where this text comes from and why you chose it? I'm really curious!! And, have you considered switching to a license that can be identified using an SPDX identifier, like ISC, MIT and BSD-2-Clause? Think that'd be quite nice :)
