That's the way greed creeps.

You could build a successful service that brought in $1 million a month from happy users treated ethically, but there will always be an insatiable psycopath whispering "if we sold our user data, we could make a extra $100k each month".

So one ad becomes two. Users are tracked and the information sold. Algorithms are created to make services as addictive as possible, because "one more video" turns into "4 more ads".

However many apologists may post about poor, destitute Google being unable to feed their children because people aren't watching enough ads, we're absolutely correct to oppose that endless creeping.

There is always another sleazy way to manipulate people out of money. Companies need to learn to accept that their tens of millions of dollars profit are enough.
