I read the article. The reasons are trivial. First, old (>10 years) networking hardware may be unable to support it. All new hardware can do it, but some old stuff can't, and some ISPs haven't budgeted for the update. Response: 10 years is forever in the hardware cycle. This isn't a woodworking business, where old heavy iron is a good thing. Sensible businesses budget for returns on investment and mean time between failure on shorter time scales. Second, the labor to install network hardware replacements and perform configuration updates is expensive. Response: That's literally your job, you don't get paid to sit around and collect money. Third, and most importantly, the costs of the DDOS are not felt by the ISP. It's a tragedy of the commons. Response: Regulation, obviously, is required. If your network causes damage that the industry says you should have prevented, you should pay.
