Some pluses and minuses sed in <slrnb4vldj.60u.curt@desktop.cowboy.loc>:

Those features only, could be sold to individuals only, at a
reasonable one-off price, and with appropriate licensing

The problem is that QSSL isn’t convinced enough that this is affordable.
OTOH they may haven’t done any marketing research on this.

Suggestion to QSSL: Mail the NC downloaders for poll if they want to buy
“additional package”. Having potential customer numbers is better
than no data.
Although I bet nobody will respond on price around $100US just for mkifs.

next time post the “privacy policy” – haven’t you been working on this??)
