Time to speak up?
Of course any of us can block FB, but it seems to me time that anyone, start going further: NOT using or linking to FB at all, explaining briefly why to any and all invitations to use FB and doing our best to quietly persuade others to follow suit.
Yes, it will sometimes be inconvenient, and sometimes lose revenue.
Some will regard it as insane, or pointless, or extremist.
But out of everyone, we are among the people best placed to understand how corrosively damaging FB is.
I hope that we can persuade The Register to do likewise..
