The whole purpose of all these Google services is to collect private data. Very few people actually realize the scope and power of the data they are collecting and how it is used, and how they plan to use it when they will have the technical capability. If they would have it written out in clear text exactly what they do with this data, and what they can do with it in the future then nobody would use their services. Therefore all these services are deceptive.
It’s easy enough to Google literally any of them and read substantial numbers of articles on their practices:
For example, AdWords misrepresents clicks by slow rolling fraud mitigation and Google is quite deceptive about what various statistical measures and advertising practices actually deliver.
As another, YouTube has a quasi-DMCA process while feigning that it’s a safe harbor purveyor of information, while in fact maintaining an editorialized anthology. This quasi-DMCA process is frequently used to steal ad revenue from creators through acts of fraud which Google’s automated systems and lack of human support (intentionally) don’t mitigate.
It’s just not worth my morning to document all of it, because it’s literally a story a week for years. And a dozen stories a week for the past few years.
