And google is entitled to infer that you're using it and serve you different content, or none at all.

And I'm entitled to publicly shame software engineers who implement this kind of stuff for Google.

Best of luck. I actually hope it works, but I'm not optimistic.

I'm pretty sure it won't, given that it hasn't worked so far for much worse stuff (like people implementing the panopticon at Palantir).

It's not possible to shame a group of people who can't even agree on baseline ethical issues around their profession. For every engineer who refuses to work on guided missiles or the Torment Nexus and would feel shame to do so, there's another engineer who would find it an interesting technical problem.

When such things work, it's not because people who do it feel ashamed, it's because the society ostracizes them so much that it becomes actually inconvenient to function in it.

Oh, and it is an interesting problem. In the abstract.

You should instead support businesses with a business model that fits your philosophy and try to persuade other users to do the same. If you aren't helping make other business models successful, you aren't really achieving anything.

They are if you use their service. You agree to their terms when you want the services they provide. Of course, you can violate the terms of service, but that puts you in the wrong legally and potentially morally, depending on your specific moral values.

You aren't entitled to their service, but they are entitled to your data (as allowed under the relevant jurisdiction) if you choose, of your own volition, to use their service.
