One way to allow for this would be a license that says if you sell them through an LLC or corporate entity of some kind, that should require financial support but if it’s you selling them in your own name or as a single owner business, with your reputation and liability on the line, then you should not be required to provide support. The other thought to include in a license is actual money earned from sales. Once a company earns, for example let’s say $1,000 or 1,000€ a month in profits, that’s when the financial support license kicks in and requires payments to the open source authors. Of course, that would require high earners to report their earnings accurately which is a different can of worms.
You use “directly” three times. Remove all instances of the word from your post and reread it. Does the post make sense to you still? Does it have the same meaning?
I am not trying to be a dick, I want to make sure the word does not have a meaning I am not aware of in this context or if Linux is installable to a USB drive ‘indirectly’ but that does not make sense to me.
Can you rephrase what you are trying to do?
