What it means is that your devices and browsers are constantly pinging Google under the guise of "serving static content to speed up connection". This is where each of us needs to determine what makes sense and what doesn't.
If I'm hitting sites not owned by Google, why does Google have to know about it? And even if they "need to know", which they dont, why do you have to check so many times in a row in such short periods of time?
Its all about knowing what you're doing at all times, which comes with the added stress of them using up your data if limited, and slowing down your connection, however slightly it may be.
Therefore, to each his own. I dont like that, so I block it. You dont mind? Fine, have at it, that's your right. What I will certainly keep doing is trying to steer people away from just letting Big Tech do whatever they want, and that's done by informing what these companies do, how and how often. Some people will care, and maybe even do something about it, others won't and maybe even try to convince others that there's nothing wrong with that.
Again, to each his own.
