I worked in advertising technology for a full decade and worked with google's advertising solutions for a lot of that time. They talk a lot of talk, but their only strength is the reach of the data gathering they do, and the amount of ad space they own in youtube as a "walled garden". Both are tied to people using their services, and they have a lot of controls because of europe to handle "user data validation".

So, the best way to hit google where it hurts is to do the following:

1. Cancel your gpay, youtube and gmail accounts
2. Delete chrome and go for a stable opensource fork or a tor based browser
3. Wipe your google data from your account before you go to bed at night. Every day clear your cookies too. Do this and google search will be nonsensical, so youll adapt by not using it. Duckduck is decent.
4. This sounds odd but with effort it will work better: dont use adblockers. Instead... 4a. Flag any ad you see as inappropriate if you are overseas and the link has the words google, or doubleclick, or dbm in it. Not sure you can do this in the usa as well, but this would invalid the ad spend made on you. 4b. If you want to ger creative, google actually lets you say your interests and demographics for them. So you can force google to think you are a 90 black woman with 200 grandkids and a penchant for teen dramas and hardcore versions of hentai cosplay reinactments if you want to, and they have to accept that as the facts.

If 60m americans become noisy ass ghosts on the google network , google's value as an ad network, its primary revenue stream, will start to falter. It will take 90 days to burn their historical data, and after that everything will be random successes for them. That will hurt, especially if everyone does it.

They are happy to defraud america, i say defraud their data systems and inference engines. Give them crap for their algos to eat, and it will hurt advertisers, who will leave google for other platforms. If youtube loses millions of its base, its value will tank as an ad inventory set and ita data will become worthless for spending against. Their competitors will eat the share away, wrecking the stock value.

Use the engine that is capitalism, and exploit the weaknesses of all algos and data - garbage in equals garbage out for the algo. Give their pms a nightmare aacenario they cant fix without blowing your ids away internally, and if you keep refuting their details on demos, everyone will get pissed on the analytics side fast. Corps expect results in their media spend, and tend to plan a year ahead. Keep this up for long enough, and voodinate it well, and we can kill google economically in 3 years.

vote with your damned feet and let silicon valley melt under its own hubris. Its the only real vote on earth, today. That's my advice.
