"The internet" is as present in my life as I want it to be. No one is forcing you to install apps which notify you, or to post on social media. That's your choice.

Thus proving my original point: the immediate reaction is to try and externalize the problem, despite the fact that it is entirely being driven by your own choices.

You've carefully constructed your example once again to make yourself the idle victim: powerless against those evil corporations who are just forcing those alluring social media sites on to you. As though you exert no control or dominion over your smartphone or it's applications, or how you use them.
