Long time hipchat user here (both DC and Cloud), the rollout of Stride rubbed me all kinds of wrong ways. They 'replaced' HipChat w/ Strie but didn't keep many of the same features/integrations and then FORCED you to switch by a deadline. I get upgrades and progress, but how about rolling upgrade, swap out the client, move everyone over automatically and not pain your users? For my team, we said screw it and 'migrated' to Slack. Give us a chance to switch, we switched.
