Where to sell scripts based on the MIT code?

Question

Business Informatics

I modified the script based on the MIT license.
As a result, questions arise.
1.Can I sell this code? According to the text of the license - yes.
2. My selling script is released under any other license (mine) and the freedom of the code is lost, even inherited? Those. the one who bought it cannot resell, etc.
3. Am I required to indicate the licenses of the legacy code? Specify in the file at the beginning or just in a separate file? If not specified at all?
Naturally, this is all of interest in an international context.

IANAL.
1. Yes, you can sell both modified and unmodified scripts licensed under the terms of the so-called. "MIT licenses" (at least the two most common ones: Expat and X11), as well as under the terms of any free license: GNU GPL, GNU LGPL, Apache v2, etc.
2. "MIT licenses" do not allow you to change yourself in the truest sense of the word. But they allow you to sublicense the work under more restrictive terms, including to the point of forfeiting your freedom.
(Of course, there is nothing good in creating your own non-free work based on someone else's free work - those who find out about it will definitely not remember you with a kind word, but in this case you have the right to do it
. )are obliged to take care that your users have access to the original form - the program has been assembled into machine code / bytecode, or the script has been obfuscated for compression purposes - OK.
3. But you must report the material included in your work under one of the "MIT licenses" and provide, in addition to the name of the copyright holder, the full text of this license (including the disclaimer of warranties). And you need to do this in such a way that it is clear that this is not a license for your entire script. However, this is already a requirement of your selfish interests, not a license.
