Not discounting mental health effects of advertising assault, but both of those things can have direct life-threatening impact, so I'm not sure they're a valid comparison to choosing a refrigerator. You don't even need certification to be an auto-mechanic in my country. That said, the previous response about subsidized refrigerators forced me to reconsider the issue as a purchasing choice.

I still don't think it's realistic to expect the software engineers implementing questionable features to refuse to do so, or be punished for following orders. Sure some might choose to quit and work elsewhere, but their seat will be filled by someone else.

If it's not a consumer choice issue, in a future where most refrigerators are subsidized by ads, I could see a case for regulation, but my hopes are low tbh. We already have ads everywhere, so why would an appliance like a fridge or washing machine get special treatment? Personally I'd love a world where there's no ads except in dedicated opt-in places, both physical and digital. I have zero faith I'll ever see that.

How do you propose we stop our impending doom? Where are your proposed consequences coming from? I think this is an interesting social issue, I'm open to having my mind changed, and I'm trying to have a real discussion, but if you've just got more snide "bro" comments, we can leave it here.

Real professionals don't get to use the Nuremberg defence. A pharmacist cannot blindly give an absurd prescription, no matter what the doctor orders. A nurse is expected to double check dosages. An electrician can't just short circuit a fuse that keeps breaking just because you tell them to do it. These professionals can be held criminally liable if they don't follow regulations and good practice.

As an industry we need to grow up. The stuff we do has a real effect on people's lives. It's not just fun and games any more. Other industries have things like professional registers and regulators. We need to accept that being a software engineer is a powerful and privileged position and with that has to come responsibility. Privilege without responsibility is an injustice.

As for how to actually implement this I would start with ethics and safety being considered a primary concern in software engineering. Computer science is academic, but if you want to be software engineer you need to demonstrate some understanding of ethics and safety. I'm talking certifications, professional bodies and registers etc. Things other professions have had for decades.

The free market approach seems lovely in practice. Do you know what the definition of a free market is? Part of it is that consumers have perfect knowledge. That is, they know everything they need to be able to make the correct decision. How many people do you know with perfect knowledge of anything? You've already identified the other problem which is a free market requires low barriers to entry, which fridges and electronics do not. A free market is a theoretical concept. It's no more real than my hypothetical regulatory system.
