Hi,
I suggest that there should be a free version of oracle forms like there is with Apex and ADF. My suggestion is about a release that's features are limited comparing to a full version. I know that could be hard to get done and requires work from Oracle employees. So, I could suggest that Oracle set old versions of Oracle Forms free for production use i.e forms 6i version for developing desktop apps and maybe one of the old web-based releases.
The benefit from that is that small developers/companies that are not able to afford license costs of Oracle products(companies in developing countries which still uses windows 7 till now) will be able to use a product of the company which will eventually benefit Oracle because the name of the company will always be alive when small developers/companies develop apps and deploy it. Which could also grow their business and increase their income which could lead them to consider buying a license for non-free versions for developing a bigger apps.
I hope you like the idea.
