雖然 Slack 這邊新聞稿的標題是「Atlassian + Slack」，不過不是直接買下 Atlassian，而是收購 Atlassian 下面的兩個產品，HipChat 與 Stride。另外 Atlassian 這邊的新聞稿在這：「Announcing our new partnership with Slack」。
HipChat 與 Stride 現有的使用者都會被轉移到 Slack，並且會終止這兩個產品線：
As part of this partnership, Atlassian will discontinue Hipchat and Stride, and provide a migration path to Slack for all their customers. We are purchasing the IP for Hipchat Cloud and Stride to better support that path to Slack, while Atlassian is making a small, but symbolically important investment in our business.
As part of this partnership, Atlassian has made an equity investment in Slack, and Slack has acquired the IP for Stride and Hipchat Cloud, both of which we will discontinue. We will also be discontinuing Hipchat Server and Hipchat Data Center and working with Slack to provide a migration path for customers of all four products.
對使用者算是好下場吧，至少不是被完全不相干的單位收購... (像是前幾天的「TRON 買下 BitTorrent Inc.」)
