I worked in the high-tech software industry for a number of years; and, immediately made the decision that I would remain as anonymous as possible. I figured that the less of a personal profile my employers, or potential employers, could assemble for me from the Web, the better.
Consequently, my belief is that the voluntary measure that would be most effective is to not use those social media applications, and as few other products from those companies as possible
For example, I have a Facebook account and password; but, my profile is empty, except for my birth date. I never respond to “friend” requests. The only time I log in to Facebook is if it’s the only way I can see something or respond to someone’s statement that I’ve read somewhere; and, that’s only been necessary twice.
I frequently look at videos on YouTube and have a password; but, the only time I use the password is if I want to ask a question of the poster of a video.
Google’s been on my “ten-foot-pole” list for around eighteen years, ever since it became apparent to me that their sole purpose in life is to harvest and sell personal data. None of their apps are on my machines. Once in a great while I will use Google Search; and, once in a while, I’ll use Google Maps; but, I never sign in.
YouTube is the only service that I would definitely miss; so, I’m hoping that Google doesn’t screw it up any more than they already have since they purchased it. The other service applications can die a quick death, as far as I’m concerned.
