I'm throwing my $0.02 in now too.
A lot of people seem to disagree on the "subscription" model. Sounds fair enough to me, but I can see why people are throwing fits.
Megatronx had an interesting idea which I were also thinking about. What if you had some sort of advertisement like Spotify? Maybe not as intrusive as Spotifys (no sound for instance), but merely as a way to gain some small revenue from the free version and a less direct way to push viewers to buy the indie/commercial license. Add to that an advertisement space on the download page for the free version (though that might be pushing it).
I bought Renoise last fall and their licensing deal is pretty nice. Their demo has pretty much all features (even save) enabled with the exception of "render song", and the ability to use ASIO drivers. I played around with the demo for two months before I bought it. Mind you I bypassed the disabling of rendering by simply connecting Audacity directly to my sound card and simply recorded what played on the speakers.
I still bought it though. Their license worked like this. You pay �58 ( plus VAT ) for the license and for that you get a sample kit and free updates for a whole version. I bought my license at 2.6 so I have free updates until they hit 3.6, at that point to get further updates I have to pay an additional fee. But that fee is smaller than the first one, �48, because I had already bought the license once. Now, C2 doesn't use version numbers anymore but I think it could still be applied. But then I guess the rate builds are released would have to be more regular.
I had another idea, I'm just throwing these out for thought, not saying they 'should' be used.
If people are really stingy and want to pay even less ( ), what if they could opt in to having splash screens and such, insteead of having it simply be a nagging thing for free users?
By opting to allow splash screen and similar things they would get an X% reduction on the license cost when they buy their license. That way, you'd still sell a license, albeit at a lower price but with the benefit of more advertisement.
