This reminds me of another ISP scam. Around 2010, my ISP would occasionally inject pop-up ads into clear text HTTP pages. Apparently the solution was to call in a complaint. The customer support agent would act surprised (lol) and promise to investigate, and no ad would be delivered to the complaining customer afterwards.
They implement this at the edge, so bypassing the nameservers bypasses the silly search page and doesn't change the authoritative domain name. Verisign was changing it at the root, for everyone.
A difference of degree, not kind. This technique is the predator of the attention ecosystem, singling out the "old and weak" if typos imply weakness!
An angle no one has mentioned it how this played into googles dominance. These predators made it legitimately safer to type into a search box than a URL bar. At least for a little while.
Do you have an actual disagreement to communicate, or just thought-terminating dismissal, because it seems that typos would be more frequent for users with poorer attention to detail, which sounds to me like the kind of user that is more likely to fall for a scam.
So yeah, preying on users who make frequent typos would also serve to target less observant users, who have the potential be exploited more easily than the general population. AKA: typos imply an exploitable weakness
Case in point: Verisign and Telekom squatting on typo'd domains to extract revenue from exploitable users.
