I’m not here to debate that, but fact is we live in a world with copyright and thus licenses are necessary.
I appreciate that you are open to copyright being evil and you are doing your best to follow the rules of the land.
However, I do want to plant the seed to consider that your statement would also apply to 1830’s Mississippi (“I’m not here to debate that, but fact is we live in a world with [slavery] and thus [Freedom] licenses are necessary.” Freedom licenses were licenses black people were required to carry if they had been freed from slavery.
Copyright and licenses are on the wrong side of history.
how we can possibly continue to employ developers when our work is given away for effectively free.
I think you would make MORE money with an Early Source. Set N = 4 to start. That means that you publish the source code to Sublime Text as it existed in 2020.
Many young people and amateurs would use it. You replay the git commits so they can keep upgrading as well, except they are always 4 years behind.
Then all your paying users would get a link to the latest binaries or something. There’s obviously some important details to get right, but it could work.
Could be a win-win-win.
There is zero reason from first principles why there is ever any need of “licenses”. Not in theory, not empirically. Tim Berners-Lee and the World Wide Web, and D. Hipp and Sqlite, are doing just fine with public domain.
