definitely, I'm disappointed with slacks responses. We did a trial and have had some correspondence with their support team which has been excellent to date. So I assumed they were above some of this silicon valley elitism. I'm glad to see this kind of public disclosure. We have been a customer since that initial trial, we stopped using hipchat.
To be fair, most of the bad correspondence was from 2014. Their new representative 'Leigh' appears to be doing excellent work.
Also we're still happy users of Slack, I would just never trust them with secrets :-).
