My biggest issue is with the UI though. Without watching the video I wouldn't know what half the buttons do. Many of them have multiple actions/states and there are no labels or tooltips for buttons.
Forms do have labels, but you have to click an icon to read them. It seems the only benefit of this is that you can also see what the label is in French, but unless you're translating the app, most users would prefer to just see the label in the language of their choice. And there are some dialogs where just English text is shown, so this isn't entirely consistent. Maybe I'm totally missing something here, but I think simply having a user select their preferred language isn't something that needed to be innovated away.
Look at Elixir's slack for example. Since it's a free tier, you can't view older messages that can be beneficial to someone. And Elixir's slack channel is not going to need fancy workflows, web hooks for CI, gitops capabilities et all.
What are you talking about that would be bad for your employer to hear to begin with? Non-work-related discussions should never happen on work machines.
My employer might be.
Slack absolutely has a way to export all data (including private direct messages), it's documented here: https://slack.com/help/articles/201658943-Export-your-worksp...
Since your employer would be the organization owner or admin of the Slack account that would allow them to check into everything that anyone has ever said.
It does seem to have subscription tiers, it’s just that the first tier is free.
