I’d describe it as parasitic disruption. The scam analogies are on point and fine for rhetorical purposes, but they imply a degree of intentionality which is not necessary for some tech to be parasitic.
Say you invent a new type of electical power line that’s more durable and power efficient than the existing type. The materials are also ten times more expensive than for the same length of normal power line and the only factory making this type of power line can only make enough to fill the needs of a few small customers with special needs. Meanwhile local government in Eriador is planning the electrification of the Shire community when the well-meaning councilor Brandybuck mentions this new type of power line he read about in a magazine. Perhaps the council should wait and see how that develops before committing to building power lines that might be obsolete the moment they’re put up.
Neither you nor the councilor are deliberately using your invention as a tool to stall electrification of the Shire, but the same effect happens anyway.
You point about property B is a pretty good one. My hunch is that tech follies like these are related to economic bubbles and share similarities with them. I’ll postulate that most parasitic disruptions go hand in hand with economic bubbles, but not necessarily all of them.
Another, a little more snide name I came up with while writing that: “free drinks tomorrow” tech, after a popular sign seen on the walls of bars around the world.
