Edited to clarify.
Things to consider: How much of your data would you be comfortable letting Lemmy sell vs Reddit? If Zuck treated users better, would you be more accepting of Meta monetizing your data every way possible? When it comes to using something for free (tangible or intangible) do you accept a company selling your personal information if their practices align with what you feel is fair?
So do you feel that companies should never sell/use a person’s info even if the product is free? Would you accept greater amounts of advertising and the use of anonamized user data if it meant your personal info was never sold?
