alt Hacker NewsOn Microsoft, Apple, and game consoles, it is still pretty common to pay for development tools.
Also pretty common in enterprise tooling, which is the market of tools like Delphi.
The alternative is everyone getting surprised that their favourite free software development tools (only free thanks to VC money), eventually goes away.
Mostly Microsoft (inertia, you're already paying) and game consoles (expensive SDK/dev-kit licensing with NDA crap).
I see it less on Apple platforms except for published applications and niche tools.
