You get some weird shit depending on company cultures.

Tools also affect it. Teams is terrible for “structural”, long-lived team chats (oh, the irony!) like are totally natural in, say, Slack, so tends to push more stuff into meetings and ad-hoc group chats. It’s a really bizarre (and endlessly irritating) design choice. You also can’t “digress” within the same channel like you can in Slack without spamming the main chat.

Worse tools = people use them differently (worse) like calling more and doing more private messaging. Add corporate, division, and individual cultures and preferences, and you can get all kinds of weird stuff going on, including the bare “hello”.
