Yes of course. It works perfectly for what it was meant to be: good enough so people won't switch away from MS ecosystem to have a group chat. Nothing more.
Teams is actively developed along the lines that deliver greatest value to Microsoft at the expense of their customers (a business model increasingly popular these days):
1) implementing corporate-nerfed versions of vanity features introduced by competitors in group chat space (Slack, Discord);
2) broader integration with everything else in Microsoft's corporate ecosystem.
You can be excused for thinking Teams is just a crappy chat-based interface to SharePoint, because this is what it effectively is (Don't have SharePoint? Sucks to be you.).
Copy-paste? What are you? A corporate smartass? There's no budget left for smart-ass features - it's all in lock-in features, where the RoI is much greater.
