The C# world also has quite a few paid libraries, especially for UI stuff.
Quite a few years ago I worked at a company using Delphi, and judging by their homepage they are still using it. A company making industrial machinery, with a tiny internal software department for the software for provisioning and maintaining the machines, as well as the control room software. Usability and development velocity is more important than looking hip, and easy access to hardware interfaces is paramount. And compared to developer salaries those license costs really aren't that bad
On 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.
(Technically it is optional if you don't need to ship signed apps or submit to the app store and you don't care about the rest of Apple's developer program.)
They have free community edition. Main restriction seems to be: "If you're an individual, you may use Delphi CE to create apps for your own use and apps that you can sell until your revenue reaches US$5,000 per year."
