Ok I agree with these failures, but don't you think that its a PR people problem? Perhaps executives and upper management? Sales people are just doing what they are supposed to do. Sell Atlassian products.
You and the person you're replying to are using the word "Sales" differently. GP is using it as "Sales Representative", a la Jim Halpert, whereas you're using it as "Outbound Sales", like Glengarry Glen Ross.
