people doesn't really care all that much about giving information to big tech

I was one of those people some time ago. I remember doing it deliberately and saying "what will they do to me? Offer me a product that better suits my needs?"

I never had any issues because of that...

right now I decline each time, the more work it costs me, the more motivated I am to decline every single marketing consent.

I do it out of spite, because of all the enshitification happening to services I used to like, and I just try to make their life harder.

I really hope that Google will, some day, miss one cent needed for some huge multi billion deal thanks to my resistance! ;)
