Don't be a dick.
Hey I understand you are/were upset. You rushed out and made an inaccurate and POV laced change to the wiki, and it got reverted. That's the way wiki's work; scjessey is not a DreamHost employee, so your retort here is as ignorant as it is unecessry.
It might help you to understand why they made this change if you re-read the newsletter announcement. An explanation was offered.
As far as "continuously promises a service" and "entered year long contracts" a re-read of your TOS might also be in order - you might want to get someone to help you understand that if it is confusing.
I agree that such notice might have been a better way to approach this change, and that your feelings on that are understandable - maybe you would be more successful at communicating your feelings if you had approached the matter from this perspective in the first place.
At any rate, as I read the announcement, it doesn't look to me as though this will affect any users you have already established in the slightest - only new users going forward, so you are not really undergoing any change at all to your existing service.
If this won't work for you going forward, then of course you have other options.
