Trump and Johnson: Allies in Disruption

I'm losing my grip on the English language. maybe my interest, too; since it no longer is used the way I like it.
what's the deal with disrupt and disruption? when I caused a disruption in class I was sent to the principal's office. you never wanted to be called a disruptive influence at work -- you could lose your job. communists are disruptive, not patriotic Americans. but now it's apparently a good thing to be disruptive. disruptive marketing and disruptive startups and disruptive planets breaking us out of orbit. my son does stuff with social media, which makes him enough money to buy a big house freshly painted and with clipped hedges -- he asked me to write 500 words on disruptive advertising for one of his innumerable blogs. "what's that?" I asked him. "it's anti-advertising; going against the perceived wisdom and experience of marketing to establish a whole new level of consumer consciousness" he said. I turned him down. I told him there's no positive in disruption. not in this world. and I would stick to my guns and deplore disruption in high places and low, until the forces of disruption come to get me.
