It is amazing what you (commercial) software you can get today for free:

• Delphi
• Visual Studio
• IDA
• if you are a student, you can get lifetime (!) access to all of Microsoft’s products, provided you don’t use them for commercial purposes

I for one welcome our overlords prefer the open-source alternatives, because I know that I can read the source code (the ultimate documentation) and poke around with it, but even if you aren’t an open-source enthusiast, you can thank them for creating a marketplace where such altruism is expected from companies.
