I think you might be overestimating that market segment tbh. I’m sure there’s some folks who Hardline like you, but I’m sure that number is exceptionally low by percentage.
Also, I think it’s totally valid to not want to share your data with a company, but I’ve seen a lot of confusion before as though Google is selling your data and just for clarity, that’s absolutely not what they do. You don’t want to have your data in their ownership? Valid. You don’t want them to resell what they collect from you? Unfounded and a literal negative business value for them.
Where did you see this 50 third parties request? Maybe I just missed it on setup?
