Stop using Slack already!

This is a pet peeve of mine, so it'll be really brief.

Slack is a proprietary software for businesses, for the enteprise world. They have a free plan to allow people evaluate the product. Slack was bought by Salesforce in December 2020. Salesforce is one of the biggest business solution provider.

I think we can all agree on that, I hope so far nothing controversial.

Now, why in the world should a new Slack workspace be opened for every small projects kickoff discussion and brainstorming?

A room on matrix.org is perfectly fine for that. An IRC channel, even! It takes exactly the same number of seconds (if not less) to get together using these solutions than accept a Slack invite, create and verify the account. The only difference is that everytime you enter in a new Slack workspace you are harassed by all the "welcome" nags and popups.

If a project then starts and gets momentum, it may make sense to use a more business-oriented solution (Slack has many interesting features and integrations).

I'm not even pointing out any of the non-technical reasons to not use Slack (plenty of them ¹), I'm just pointing out the fact that we mindlessly use the same products we use for work also for non-work purposes.

I see what these solution providers are doing: it's the same story since the time people learned to use MS Office and now are not willing to use anything else:

I use it at work, works fine, it's free (*) so I'll use it
also to discuss a couple of kickoff ideas with my buddies

(*) conditions apply

I'll cut it here because I promised to be brief :)
