> Otherwise, the future is bleak for your smart toaster

Well, no. Smart toaster is going to be just fine. And that's the core of the problem here. Much like it is the case with polluting diesel cars, owners are reasonable happy with their purchase and simply unaware of any problem (until/unless product is recalled). And even being aware, there is very little incentive for owners to address the issue of their property subtly contributing to harming somebody else.

And same again with much-needed BCP-38. It adds very, very little value to the ISP who implements it, so many never bother to. Yet less-then-universal roll-out of BCP-38 hurts Internet as a whole.
