I just don't get it

There have always been powerful business entities in history and there will always be - they could be banks, oil companies, rail companies etc. The difference between these companies and tech companies is this - tech companies are extraordinarily powerful and pervasive. It is very, very difficult to avoid using Google for example. Even if I stopped using all Google products today, I still have to email people who are using gmail. I don't use Facebook, but I am pretty sure they have tons of info on me, because of shadow profiles. And so on.

"Big tech" as you call them, they have unbelievable amount of power over our lives than other "big" whatever. That is why people are worried, and rightfully so.
