Because I'm a reader who knows something about this subject, this seems to me like a beginning basic introduction, where a reader less informed might judge differently.

Whether intended for a general reader or a specialist, however, the essay would certainly be improved by discussing the difference between copyleft licensing, where the legal conditions on use of the work are designed to protect users' rights, and "permissive" licensing, in which the developers of new programs or versions of programs have a right to render their own versions proprietary, thus ousting users of their rights. A discussion of the difference would be informative to general readers, and would help more expert readers gain confidence in the analysis.

Similarly, I think you would improve the next draft by explaining more fully why the "serious marketing budget" (which, for example, Google and device manufacturers certainly have for Android) doesn't really improve peoples' understanding of their rights in the software they use, or how those rights should be protected.
