There are also many many smaller niches where software can be sold because there isn't adequate developer interest to create OSS. One example is this: https://querix.com/products/lycia (not a customer, just ran across their product).
I tried to migrate to VSCode for golang.
I mean, don't get me wrong, the situation is not the worst possible, but the only reason you would want to use that is because you never tried refactoring with Goland.
Are you kidding me? I had to go look for what is the current needed extensions for go that are still maintained, configure them etc...vs just download and use Goland.
If you can't or don't want to spend money OK, but otherwise is a non sense to use anything else.
But I want to use a concise, powerful language that requires more work from the compiler, rather than an impoverished language that assumes an IDE will generate a lot of crud that isn’t worth reviewing.
Sounds a lot like the free IDE I use for HTML and JavaScript... Firefox.
Code editors are a product where polish has high value, and users are willing to pay for that polish. I don't particularly care if my editor is open source as long as it's got strong community and great polish.
The Ultimate edition is the open source version of IJ with more plugins. However the rebranded non-Java versions like Goland aren't open source, unless you consider the IJ base. They are the core language plugin(s) + integration and rebranding code.
Then I discovered the makers of resharper made an IDE which supports tons of languages and never looked back.
As long as they don't fuck it up like Adobe fucked photoshop (and every product they own), they'll have my money.
