Its true but then again, they could provide tiers that restrict large file upload, video calls etc. I think most of the businesses using Slack are unlikely using their video call system (and more likely to use Zoom, Teams, Google Meet). Most organizations use Slack for its organized messaging system; maybe they should make plans that focus on that.
They try to pack more and more features and realize that when their customers start using these, it costs them money.
Yes. I already address that in my post. Block the features the use bandwidth.
Them keeping the _chat logs_ history hidden has nothing to do with bandwidth costs. They store the data, they already pay for that, and it's not that large to begin with. The reason they do this is to hold you hostage so you have to pay them a ton of cash. It's extortion. You can defend it all you want, but they're all pretexts, not the real reason.
