I suspect that JetBrains is trying to respond to the fact that Microsoft gives VSCode away for free and that's likely what is spurring the massive adoption of VSCode.
A colleague of mine at work, who is almost retirement age now and has 10+ years on me in the industry told me that the ONLY reason he uses VSCode is because it's free.
I'm with you, there are IntelliJ features (particularly the refactoring features that I use all the time and couldn't live without) that I just take for granted. And when I watch other devs do things the hard way in VSCode I wonder why it's is so popular. I think most devs just either don't know what they are missing, or it just comes down to cost.
I also often chuckle when people say "Oh there's a VSCode plugin that can do that." I'm not certain, but I don't think I've ever installed a single plugin in IntelliJ because it just does everything I need out of the box.
