Brilliant idea.

Source code is frozen in time. Especially as the software world moves faster, software depreciates in value / rots over time. Separately and equally importantly, depending on the use, the same source code can be a fun hobby or be the centerpiece of a giant business.

This model lets open source flourish while reflecting those realities. From what I see, a business has the option of using the software without paying - they of course wouldn’t get maintenance. They could keep people on staff supporting it or just get support this way - and this way is far cheaper.

Let’s see how it plays out! Could become industry standard.
