Don't know about Slack's videoconf, but Slack's cheap insistence that we pay a rip-off amount of money per month for storing some TEXT messages more than 90 days has continuously degraded my appreciation for it over the last years to the level of me hating it now.

They're so cheap. Just put a quota on total storage or something, that actually map to their costs..

We have a Slack for a shared office of 10 people or so, we use it to like ask each other for where to go for lunch or general stuff, it must cost them $0.001/month to host, but you continuously get a banner that says PAY TO UNLOCK THESE EXCITING OLD MESSAGES all over it, and when you check what they want, they want some exorbitant amount like $10/month/user so $100/month for a lunch-synchronization tool. For $100/month I can store like 5 TB on S3, that's a lot of texts.

I'm genuinely curious why they don't have some other payment option, I'd be happy to pay $1/month/user for some basic level if they just don't want freeloaders there. Well, I wouldn't be happy.. but still :)
