I understand where everyone is coming from in this thread (I am myself using an unregistered version also ... but I'm a poor PhD student, so make of that what you will).
However, it does worry me a little that the conversation surrounding the licensing situation is not more broad and self aware.
I think there's something to be said for supporting a small and independent software company if you like/use their product (and don't want them to be owned by MicroGoogleBook. I'd like to hear more in the discussion about what makes sense for such support rather than "if it was just $10 less I'd totally pay it".
By the same token, I wonder if it'd be better if there was a more inclusive and informative approach from Sublime HQ on what does make sense for them, and what level of certainty there is around support and development going into the future. Obviously, demanding that they reveal profits and salaries and the like is unreasonable. But, maybe some transparency around how many people need to register for them to keep going for the next 3 years etc, would be helpful for the discussion. Maybe feeling like we're not just buying a license but buying into a community would be nice.
Either way, I do enjoy seeing a small Australian company being on the public stage so much in tech ... I figure it's a good thing.
