What Can Be Done?

ICANN has already created a panel to study the impact of SiteFinder, and has asked Verisign to voluntarily suspend it. Verisign has declined to do so. ICANN has the power to revoke Verisign's authority as a registrar for domain names, but as it is the largest and oldest such registrar, and the fees that run ICANN come from registrars, it seems that this is unlikely.

A petition has been created, directed at ICANN, asking them to take stronger action. If you agree that Verisign is abusing its privileged position as the maintainer of the topmost DNS database, and that violating their contractual obligations to uphold IETF standards is a bad thing, you may want to consider signing this petition.

However, that's not very practical. It is difficult to say how strong an action, if any, ICANN will take, and in the meantime, you're still going to end up visiting SiteFinder every time you make a mistake, whether you want to or not.

There are two practical, technical steps you can take so that this situation will not affect you directly. One involves talking to your ISP, the other you can perform yourself if you feel comfortable making a small modification to the configuration settings for your Internet connection.
