Slack has a nice market share, but also many competitors, many of them 100% ripoffs with the same features (to name a few, Attlassian HipChat and MS Teams... not to mention open source products).

Slack has been experiencing service degradation often lately, so I would not be surprised if people start switching.

In our team we already started looking for an alternative.

HipChat came out long before Slack.

Yeah and they've had service degradation and availability issues long before Slack also. ;-P

Did not know that, thanks for point it out.
