Remember that the community edition is open source
They are an open company and do offer a lot completly for free
Borland was .. a very traditional closed company
One of the great things about Borland was they published the source code to their VCL (their main platform library Delphi and C++ builder applications used). So you could read, learn from, troubleshoot and debug with the source code. At a time when Microsoft and most companies didn't.
And the VCL design patterns were/are incredibly elegant, and studying them an excellent and accessible way for an interested programmer to learn some real software architecture skills.
Very weird; what happened ? In java/kotlin it is as great as ever in Android Studio
FWIW I've never found IntelliJ code completion in Javascript, Ruby, or Python to be very accurate. It's fantastic in Java and Typescript.
