A classic "It doesn't suck" campaign.
Afaik, Barebones ran the first version of this campaign 20 years ago and it was a huge success.
It is so simple, it just speaks to that inner skeptic.
It doesn't say we are the best, we revolutionize software.
It says it doesn't suck.
That is way more believable and makes me think that there is a dev on the other side of that copy.
And there is something cool about this message that makes me want to wear it to the next conference.
