I think it is because of the retention policy many companies have: after a certain amount of time (3 months, 1 year, 3 years are most common that I've seen) data has to be permanently deleted. This means if you make copy/paste/save/backup harder, there is less chance people will do that. In my company messages in Teams disappear after a few weeks, emails after 3 years. You never know when your chat telling someone the app you just put in production is not fully tested and not ready and that chat will end up as evidence in court. Companies want to protect themselves, this is why they shred all data as soon as possible.
