Jetbrains is a bootstrapped superstar company, man. They don't have to answer to people like you and me. For the rest:
1. LinkedIn -> public through MSFT
2. Stack Overflow -> public through PROSY
3. Meta -> public
4. Epic -> public through TCEHY
If you want to solve this problem, start a blindingly successful company with wild ARR and then spend it how you want it to. But if you take it public, you best believe that you now have masters that look like you and me. Notice how employee ratings of CEOs correlates strongly to stock performance? That's what shareholders do too. No one knows what's right. They only know the outcome they like, not how to get there.
Personally, I think this is fantastic. They're doing a good job moving the frontier of some of this marketing stuff. That means a pretty good internal org structure that allows the eng guys to contribute to the branding stuff.
