But in terms of management I think they're making two mistakes:
1) I bet almost everyone that uses Sublime Text for production work are using the "Beta" version (3) and not the release version (2). However, version 3 is suppose to be a paid upgrade from version 2. How long can you leave money on the table like this and still have a business, especially when the "beta" status probably doesn't have much meaning with your customer base? Maybe these guys have day jobs and this is just funny money anyway...
2) By remaining in beta so long and now that many people are using it... when they do pull the release trigger on version 3, that will be a very sudden expense for people that maybe have grown to depend on it without having paid for the upgrade. While everyone on version 3 should know that the day will come when that's a new license to pay for, if it rolls out as a standard update and doesn't obviously leave room to stay on the last beta version while people digest the upgrade fee... you might see a lot of people upgrade to the alternative editors instead. (OK, OK... that's a potential management mistake, not a concrete one as yet...)
