I have to disagree. Use a Linux based operating system, self-host your internet services at home, use google free android, or do a subset of that.
Its all open source and works locally.
It's all a spectrum, with free learning material everywhere. Yes, some of thr licenses and agreements are less free, but in truth, never before have so much been available. You can break that golden cage. What you put attention on matters.
For average end-users, “use a linux based operating system” alone comprises a mountain of barriers, but most are rarely even approached because they’re preempted by lack of reliable hardware support and lack of support for staple applications like Word, Excel, and Photoshop.
The motivation is not money, but to provide a benefit to society or to the people in the immediate vicinity, i.e. to be helpful and to be appreciated.
