The fact that you need to equate something most people find quite harmless (data acquisition for targeted ads) with child slave labor, trafficking, robbery and murder only points out how weak your argument is.
There are many people on the timeline of human history that believe that child slave labor, trafficking, robbery and murder are all harmless. These are all things that have been commonplace at various points in history.
If you are in an area with any population density you are sat within a few miles of more people that have committed or are currently committing those acts, with no regret at all, than there are CEO's of companies that do data acquisition for targeted ads.
All of these things are illegal for good reason, they harm people.
But, the argument is simple:
In all these cases businesses do something illegal and therefore either need to be stopped, or stop existing.
People who use this tech are criminals, and everyone knows it. Everyone has known it, even in the US. Look at how many people use ad blockers and anti tracking scripts. It is time to stop allowing literal criminals at tech companies to repeatedly break the law and face no consequences whatsoever.
It has been going on for years, and it needs to be fought just like any of the other horrible things.
