Can you please clarify what's the difference between the two?
E.g. if you fork Nano and sell or make binaries available for download for free, people have the right to ask you for the source code.
If you don't distribute it in any form, then you don't need to.[1]
With MIT you can fork, distribute and people can't demand anything.
[1]: Contrary to popular misinformation, modified GPL software can be used by businesses as long as it is not distributed.
People you distributed binaries to have a right to the source code via the same method that the binaries are provided in. Or at least that was my understanding.
In practice, this isn't a very good option to take. Much better to provide it on a "network server" as they were called at the time the license was written.
"b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge."
