First, you don't know there are commercial products being completely open source.
Second, as a user, the one has the right to put their priorities regardless of your irrelevant opinion on them being good or bad.
Finally, I fail to understand the hostility against somebody who simply expressed what they want to see in an editor, something that contributes nicely to the thread, unlike your hostile purely negative comment.
I also didn't say or imply that I don't want to pay. However, this editor will have to compete with free, full featured, mature software like vim and emacs. That's a tough sell.
Companies who don't care about the desires of future potential customers tend to fail. Maybe I misunderstood what you were trying to say here.
And you are absolutely not willing to pay that kind of money.
Hell, If you consider vim and emacs "free, full featured software", you are 100% not a customer. If you're a linux user and "every software that runs on my PC has to be open-source" type then doubly so.
And no (vim and emacs) absolutely does NOT compete with this product. And they are free only in the as long as "your time is worthless" category of free (ie. you have paid the massive upfront costs of dealing/tinkering with vim and emacs to bring it to some shoddy level of parity).
Linux+"open source/free software beggary"+vim/emacs automatically puts you so far out of the pool of potential paying future customers for basically any type of software - it's not even funny.
