You're absolutely right and I'm also horrified by the implications, and I would be even more so if the circumstances were more normal. The trouble is that Facebook is anything but a normal player and so is Google. These corporations are not normal given that they've usurped normal business practices when both governments and normal ethical businesses weren't looking and they have deliberately and opportunistically profiteered off the backs of millions—billions—of unsuspecting people who haven't a clue what has happened to their data, let alone their privacy!
This is NOT a normal situation, as these carpetbagger corporations have essentially declared 'war' on us by raiding our data without permission—and no one believes all that malarkey stuff about EULAs actually authorizing them to do so. Instead, they did do by sleight-of-hand and deceit alone, everyone knows that. This means we've little choice but to respond the best we can and in kind—and that means we have to play as dirty as them. We not only have to grovel in the ethical dirt and mud but also play by their rules or they'll retaliate and 'mincemeat' us—no questions asked.
Let's not be fooled: any corporation that can not only rival the two most dreadful corporations in all of history—The Dutch East India Company and the [British] East India Company—in its enormous stock value but also that it make profits even more quickly than they did is more than suspect, for their growth as has far, far exceeded the expectations of any normal lawful business—even the most brilliant of them by orders of magnitude! These companies are either engaged in unethical practices, or they are working in a lawless and unregulated domain, and or it's both of these. I'd contend that it's both.
Moreover, Facebook is now threatening us with blackmail, and without compunction they'll play off users as disposable pawns in this dirty war, as we can clearly see here:
"In response to Australia’s proposed new Media Bargaining law, Facebook will restrict publishers and people in Australia from sharing or viewing Australian and international news content."
It's time we acted, and the Australian Government has taken the first step. I grit my teeth to say it, but it needs our support this time around.
