The average person is fine giving up their data and time in exchange for entertainment and convenience. Free software is good but it comes at the cost of time, you have to learn and be at least semi-competent with a terminal and/or Linux to truly use most FOSS stuff and it’s just beyond the average person. They either don’t have the interest, or don’t have the capability to learn it and for all intents and purposes those are fundamentally equivalent.
Honestly, nothing “bad” has happened to most people as a result of data harvesting. The Equifax breach got a ton of people, including hardcore privacy nerds. There’s just some stuff you can’t turn off to participate in modern society.
Only geeks seem to elevate a computer to some type of religious thing that should be more than just a tool. This is coming from someone who started coding in assembly in the 6th grade in 1986.
But in the year of our lord 2025 at 51, the computer and technology is just an enablement tool for me to accomplish something else or a means for me to trade my labor for money to support my addiction to food and shelter. I have a dozen things I would rather be doing after I get off of work than futz around with technology.
