Possibly, you do (based on experience).
Agreed. If you're savvy enough to have a problem because of this, you're savvy enough to a) Use another set of DNS servers or b) Use your own local resolver.
For awhile, Comcast blocked/redirected all DNS queries, sending them to their own servers. Then, their servers didn't work properly.... Comcast still blocks port 25. And last week, a locally well-known person was blocked from sending outgoing port 25 email to their servers from her home Comcast service. It took some days to find out that Comcast had (without any notice) turned off her outgoing email (Monday), due to spam complaints! Needless to say, her MacBook isn't sending spam -- but many thousands of folks have her email address in their (presumably infected M$) address books. The official response: We don't support Thunderbird. You could use web email instead. When you pull stunts like that, you shouldn't complain about legislation.
