Not entirely. I'd argue one of the bigger gripes in this article is Slack's inadequate search feature. That being said, I've had good experiences with Slack's search in my use after 2020. MSFT Team's search on the other hand is abominable.

Search is meaningless when the storage is so expensive. We can't afford to maintain logs more than a year. I'd give anything to be able to walk back through conversations 2-3 years ago, but it's simply too expensive for the org.
