The technical part is being discussed in the IAB's commentary on the matter. The IAB explains in detail that, while wildcards have been part of the DNS specification for twenty years, their use is dangerous and can break technology. From the technology side, the problems with Sitefinder don't come from breaking some specific RFC. They come from using RFC-specified features in a way that breaks design assumptions made throughout the net.

But even if the collateral damage is left out of the picture, the very idea behind Sitefinder is user-unfriendly, and that's the second half of the ALAC's note: Sitefinder is, ultimately, about short-cutting other error handling methods, and redirecting any users that enter non-existing domain names into a web browser to Verisign's own service, for commercial purposes. Sitefinder is designed so it becomes difficult to deploy superior error handling services that would compete with it -- because errors aren't flagged.

From the point of view of software developers, sitefinder is designed to replace a market that's open for competition by a monopoly.

From the point of view of users, it is not a superior offer that empowers them, and that they can accept (or decline) as they want: Instead, it's a service that is designed to deprive them of a choice they used to have.

It's a "service" that's being forced down users' throats.

Just like spam.
