One big difference between slack and Telegram is that Slack can and will give my data to the administrator at work if they ask for it.
ryanlol seems to be thinking only about the last hop from their data center to the device. In practice security is about a whole lot more than just checking of the coolest boxes: WhatsApp for example has had e2e encryption for a while now all while uploading every last message of every conversation to datacenters that are easily accessible for anyone with an American subpoena.
That is totally OK, I'm posting this from my old account and I don't have anything to hide from American authorities but hardly compatible with what certain people here think that just because something is e2e encrypted then it safe and good.
So why is Telegram bulletproof. That was a trick question : it isn't. But we should stick to the facts instead of trying to tear down a strawman.
Re the rest of ryanlols post: as I've mentioned before most people here don't understand Russian, yet ryanlol keep posting old Russian posts. I don't know why.
Sure, that's perfectly fair. With Slack you have to trust Slack and the admins of your workspace (which could very well be you!), with Telegram you have to trust Telegram but don't get workspaces.

It's hardly unreasonable to assume that people in 2019 have access to translation software, I also think it'd be presumptuous to directly link to a machine translated version.
With Slack you have to trust the admins (which is most often not you) as well as Slack.
With Telegram you have to trust Telegram.
I trust none of them much but there's still a difference. Also as far as I am aware Slack has never ever pointed out if they encrypt their data at rest which leads me to guess that they don't do it.
But hey, we almost agreed here.
