I wonder what happens if people en masse started doing it, and they block a large share. Forcing talks about open standards, or pushing people to Telegram / Signal. No, I'm no fan of Telegram, but the plethora of bot options make it extremely interesting for all kinds of usecases. Much more interesting than WhatsApp currently is. Hopefully Signal would embrace such tooling, too.
