Now, take a look at the Visual Studio Community license terms[0]. They, too, have a revenue restriction but it is $1 million but they also throw in a PC count of at least 250 PCs. Once you hit that threshold you will have to spend $499 on the lowest paid version of Visual Studio in order to keep on making your software.
That said, if one is wanting to learn Delphi then I would recommend Free Pascal with Lazarus instead as it handles cross platform easier than Delphi does and it is free.
The only reason I've started with Delphi back in the day (and loved it) was because everything was pirated in Ukraine circa year 2000, so nobody would even care about licensing/price point.
I also think Delphi Community version is too little, too late with such a good and cheap alternative.

One thing I liked was how quickly one could bang out a simple GUI application. Sometimes, that's all I need.
