On July 18, 2022, Slack announced that starting September 1, search history for organizations on Slack’s Free plan will be limited to just the past 90 days of message history. Instead of a 10,000-message limit and 5 GB of storage, we are giving full access to the past
I agree, but the reality is often either no documentation at all or chat history. Documentation takes time and effort, and employees are often disincentivised to write it as it makes them easier to replace.
Oh, I am aware. Doesn’t mean I have to like it, though! But on that front, you are correct: better something than nothing.
And Slack knows that as well, which is why they hold the chat history at ransom / behind their paywall.
