I agree with dangers of non-free SaaS software in education. But how does use of free software exclude use of high end devices? Moodle (frontend) and Matrix clients require as much hardware resources as WhatsApp. Is there a specific point being raised about non-free software and forced use of high-end devices?

Edit: After reading the linked message, I think I get a better idea of what it means. However, unless there is a direct link between non-free software and hardware resources, I feel it is better to rephrase it as:

Many are reluctant to use software like WhatsApp due to concerns about privacy. It would be unethical to force them to use it or act as agents of these software.

It does not, only dependence on non-free software and services is eliminated by switching to matrix. But matrix or moodle can be accessed from any computer so people are not forced to use a smart phone, for example a public computer in a library could be used.

That's a good point. However, this line feels counter productive: "Besides, there are some people who don't like to use high-end technology at all". Makes it feel like teachers are resisting change. How about something like this? "This also forces teachers and students to acquire high end devices which they may not prefer. There is no option to use, for example a public computer in a library"

It is only a first drat created from an email by Nandakumar. It is no way in a final state, please edit it as you see fit.

Thanks! Will keep that in mind. Didn't want to edit without consulting.
