It's pretty evident that you're a new DreamHost customer, or you'd know that snarky newsletters are a DreamHost tradition going back over a decade.
It's basically impossible to write something that's not boring that doesn't offend somebody out there. That's why, as staff say, it's easy to unsubscribe. Newsletter unsubscribe links are usually preceded with some super-snarky line practically begging you to click unsubscribe, for example:
P.S. - If an eternity of bliss just isn't for you, consider unsubscribing:
P.S. - Please read Wool by Hugh Howey. Or unsubscribe from this awful, awful fan fiction here:
P.S. - The Internet's seedy underbelly is strewn with newsletters full of offensive, worthless content. Help me clean this place up and consider unsubscribing from this filth:
P.S. - Pull the lever. Unsubscribe here:
I for one LOVE the unconventional DreamHost newsletters. They're fun to read even if the jokes sometimes miss the mark.
If you're offended by businesses making political statements or engaging in politics, then you'll need to do thousands of hours of research in order to figure out how to set up relationships with truly apolitical businesses.
Good luck finding those... there aren't very many of them.
