I'm somewhat bummed that Limetext [1] seems to be dead. I like Sublime, but I don't want to rely on nonfree software for my work. I switched to vim for now.
Usually paying for something helps it not to die, like limetext, for example.
For my work, I'd rather pay for something I rely on to increase the likelihood of it staying alive and keeping up with the work I need to do.
It's amazing how people still don't want to pay for software.
Now you're going to ask: How is it possible to support the four freedoms and still charge for the software?
And my answer is: I have no idea, and I don't care. It's not my job to come up with a business model for you, I'm just stating my requirements.
I don't think it's that big of a deal for a text editor, though.
One thing is if you're a designer and all your files are PSDs and you're locked in with Photoshop, but if Sublime Text dies you still have lots of other editors that will open your plain text files: Atom, Eclipse, etc.
You can always help pay to keep an open source project running. The same thing is a lot more difficult with closed source software once its been abandoned.
1, 2, 3. The violation of Freedom 3 is somewhat ameliorated by the plugin feature.
