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?
Our societies have a tendancy to be more authoritarian, autocratic and consumption driven. The way the corporations are using anyone’s data is not transparent and there is no accountability for it. There is also no monetary reward for the use of my data.
Therefore, I prefer to use open source apps and federated SM.
So to answer your question, I would like transparency and accountability about my data usage, as well as compensation. And no I would not like more ads. Since I realise that my preferences are impossible, I try to make the switch I referred above
