I think we're talking about two different things here. All that I'm suggesting is aimed at keeping and widening the LFS community, getting the "new blood" and bringing back the old one. I believe it is the more important thing today, starting in demo, where changes could be simple yet far-reaching. From this perspective, 75% of demo people is immense force, half the life in current LFS.
If you're saying that 75% of 0 is still 0, you take the pure money approach, and, simply put, I do not believe it will work, especially in the long run. Yes, a few hundred people will get license if forced to, which could make devs happy, but LFS community as a whole would suffer and bear the consequences.
Of course a view of one of the core developers would help, because it should be backed by tangible data. For example, what was the license buy rate and demo/licensed people online numbers before BL1R and BL2R were taken out of demo and after? Did it mean any change of tendency, and in what direction? What is the current tendency? They should know.
