Why would we need to hand off our data to Big Tech, though?

There are only 2 major mobile platforms so we don't have any choice if both decides to make money off our data.

You can nitpick on "need". Such typical HN response to focus on 1 word just to pick on something rather than the understand the whole message.

Please let's not get confrontational, I didn't mean it as a nitpick. I just think that there is a point at which we have to ask ourselves whether we truly need any of this. If all the options sucks, perhaps the only move is to drop all the options.
