I mean that people and I know it's good for "us" if ST becomes open-source. But Jon (ST's author)
has to figure out a new business model to profit from an open source "text editor" and the way has to make more money than he could make now. I consider Notepad++ as a good example for a open source editor but at the same time, I don't think the author makes money from that. However, Jon is running a company and making money is an important thing for a company .
This is quite interesting actually, nowadays you'll see quite a lot of articles talking about how to make money with open-source products but the reality is these open-source business models are intended for very pretty specific and they won't apply for many type of "casual" software there. For this particular case, I still think the same than when this thread was opened, I really miss the point about which benefits would bring for both the company and us the users if it was open source.
I strongly believe that one of the many keys of good software architecture is having good centralized and compact team while being able to provide the right extension points to your product. Also, even if you add more elements to a system that doesn't mean the system will become more efficient.
Btw, I still consider quite hilarious one of the initial claims at the beginning of the thread, which says:
Already, Visual Studio Code and Atom surpass Sublime in features out of the box and in extensions, despite their existence for a fraction of the time. Why this exponential growth? The power of open source.
Thing is, I don't really like these pointless battless about which OS is better, which programming language is better... or which editor is better... But I'll tell you one thing, IMHO Sublime Text has had the right solid foundations that many other editors don't and that's something that's not easy to change when the product has reached a mature stage. Sublime did it right from the very begginning while other editors like VS code or atom not. Cos let me tell you, if you consider the quality of one particular editor for just the "out of the box" features... well, that's just wrong (IMHO).
Sublime strive for efficiency, compactness and delivering the right extension points and also knew how to generalize important concepts from other editors out there at the time it was released, these concept were extremely importants and nowadays you'll see a lot of derivative work out there.
So no, I'm not sure about the statement that talks about the "power of open source"... nowadays everybody consider everything should be open source as a matter of fact, I see a good point in many cases about open sourcing stuff but that doesn't mean by open sourcing a product this will become immediately superior, cos that's not it.
Anyway, many times I've thought which alternative business model I would have applied myself if developing a similar product to ST and I can't think of any cos I really think the business model has been a really fair and good one from the very beginning.
