Teams is a security nightmare, and Sharepoint as well. Access permissions are nearly impossible to grasp for normal users. The feature that all files dropped are shared instantly by everyone through sharepoint is a huge security risk. People in general have no understanding that they are sharing files with everyone that can join a Teams channel, meaning that confidential and sensitive information frequently gets added to Teams chats in "public" channels. Managing the correct permissions on thousands of Teams channels is hard to impossible, even with extra tools. Channel owners often adopt a "allow anyone who knocks" policy when they get permissions requests, because they are busy and do not really understand what they are doing. Sharing files needs to be more cordoned off for security reasons. Not harder or more difficult, just less integrated and not inheriting permissions.
