- In real life you have no privacy, but still you don't think about it (white pages, community hall inscriptions, driving license, medical history, ...), apart of white pages try to unsubscribe from any of them and see what happens. Internet made it just easier to track you.
- your safety is based on 2 things your habits and the peers that know you and are willing to lend a hand (family, neighbors, friends ...)
- what makes me feel secure about Google tools, is his business model, if they have a breach and expose people's data, they simply bankrupt, so their business relays heavily in security. (as soon as you enable 2 time factor, it becomes incredible difficult to hack you)
- what I don't like of them, they are in EEUU soil and I'm European, so I don't know if I could eventually get into trouble (like is happening in Facebook, they simply don't listen to European cases about cyberbulling, something I didn't read yet from Google, maybe because they are not so popular, maybe because they are truly Not Evil).
- so yes, I'm a product, and it also unlocks me to easily backup and access my family photos, that I can share via chromecast, or get my mails free from non nice spam and eventually find nice new products and know that I can click without exposing myself too much.
- I do have kids, and what comforts me, I can delegate to Google the block of certain images/sites thanks to their advance AI, still is not perfect so by the time they start, I'll also keep an eye. It is different to explain something bad that he just accidentally found, that place them out of his way until he has the age to understand it.
- and don't get started with the zero days exploits, the wrong architecture of some open source apps, and even the abandonware you have out there for free.
At the end, you need to trade something because one person alone can't get everything, and trust between peers is essential. And money made that trust easy, don't trust people, trust that they want the money :)
