You're free to create such software. Let me know how that business plan work for 'ya.
It is difficult to understand why some are seemingly
against user-controlled software.
User-controlled software does exist, and here are some few examples:
- OpenSuSE Linux operating system (one of many Linux versions, they are all basically equally good)
- Corel AfterShot Pro RAW converter. This is a commercial program which was unfortunately bought from Bibble by a software company that wanted to eliminate an inconvenient competitor. The point is not that the software must be free, the point is that it must be user-controlled.
- RawTherapee RAW converter
- Darktable RAW converter
- Cinepaint image editor
- GIMP image editor
Lastly; All Adobe Photoshop versions up to and including Photoshop 7.01 was activaton-free and can be backed up and installed whenever the user needs - with no ties to the manufacturer. The same is true for all Windows versions up to and including Windows 2000. These software versions may no longer be available or compatible with most recent hardware, but that does not invalidate the point which is the following: User-controlled software exists and has existed, and people have created and and still create such software. Moreover, they have made and still make money from it. As they should do.
