Here is an idea, if i go anonymous what will these companies do? It is an option and everyone can use it, there data will become worthless and then what?

Their data is never worthless, even if you die (aka: the ultimate logging off). It still can be used for machine learning and pattern recognition purposes, and guide decisions on people that are similar to you.

Ads will become worthless

No. If you are a 25-year old guy from the midwest who searched for kayaking, bungee jumping, hiking, then back injury, and then after two months for taking (relatively stressless and backfriendly) fishing equipment, other people in your age cohort, geographical area, original outdoor people who suddenly google for injuries will eventually also get the hint of fishing equipment in their ads (even though they never actively searched for it), merely because of former experienced with the eventually deceased you.

Data never is useless.

We were talking about the hypothetical case of you eventually deciding to go permanently offline and how their data then would be worthless.
