Maybe a \ufffd or two, clarifying that this is not merely a 'partisan' ABM screed? In the end you'll need to cut all deadwood, including most of this prose. But maybe a few angles here, rephrased according to your own style:

My concerns are not only regarding the furtherance of an organization which has demonstrated an unwillingness to obey US (and other nations') laws - I wish my daughter not to be subject to the bad habits which this unstable software *inculcates in its users:

* love that word - and it should hit a nerve with er 'pedagogues' :-)

The idea that computers must crash often - and then be reloaded and reconfigured, a time-wasting and negative experience. Nor the idea that the 'source code' for computer software should be secret; never examined by a wide variety of competent people, so that it may be seen to be secure enough to use in a world where (especially the monopoly software) is increasingly vulnerable to attack. This need not be 'normal experience' and I don't wish her to imagine it is.

I wish for her to become aware of the capabilities of professional and not toy-quality software, and not to be seduced by Disney-like features which add nothing to the completion of tasks, or understanding of how these tasks are accomplished.

These proprietary features distract from her learning the basic processes which it is essential she come to understand: so that she can make intelligent decisions in the future, knowing for example - what a "file manager" is - and not imagining that it is something called an "Explorer" or other \ufffdlogo. Animated pictures of papers moving from one box to another may entertain, but they do not educate.

In brief, I wish her to learn what computing is about and what "open source" means for its future development (and why) - and not simply what the current monopoly wishes to substitute for that future, perpetually.

Etc.

('Course they may well say ~ "Well!! It's good enough that our President uses it! and anyway - didn't Bill Gates invent the personal computer? yada ugh) Hard to edjacate an edjacator who's latched on to a juicy freebie, and doesn't Want to hear it causes mind cancer.
