>The big difference between slack and Telegram is that Slack can easily give my data to the administrator at work if they ask for it.
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.
>Re the rest of your post: as I've mentioned begore most people here don't understand Russian, yet you keep posting old Russian posts.
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.

Small modification:
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.
