Well, fuck. ... we raised a fuckload of money and didn’t need more. And if we fail, we fail with our full asses.

I have seen this language from other companies to which I say "no". Being professional means being able to do good work, being polite, without lying, cheating, or stealing.

I do not want them to fail yet I would never use them despite liking their product. A few other companies behave the same way.

Have they done bad work, lied, cheated, or stolen something?
