It's not a direct and honest way of asking people to pay for Sublime Text - it's an indirect way of asking people to continue to pay for something they thought they'd already bought.
I paid for Sublime Text 2 with the expectation of continued support of the quality we had during beta, but instead we have waited months for bug fixes which have never arrived. ST2 was essentially abandoned after it left beta, and now we find our money hasn't gone into supporting the product we paid for, it's gone into funding the next one.
As a developer I know this makes excellent business sense, but as a user it feels like I've been tricked. The changelist looks more like a point release, but one we have to pay another 50% for in the hope our bug reports will eventually be acknowledged. Given the past 6 months I have no confidence that'll happen.
Perhaps I'm being unfair - after all, I use ST2 all the time, and I've certainly got my money's worth out of it, even with the bugs - but something about this just doesn't feel right.
