This is old news. When this change happened, there was a lot of outrage and anecdotally many people started using Telegram and Signal. But my guess is that at least some of the people who switched went right back because of network effects and because FB and WhatsApp started putting up advertisements about how this is only about the “WhatsApp business” platform and that it doesn’t impact users’ personal chats. It seemed like a lot of people weren’t aware that this had already been happening, before the announcement to make the opt out unavailable.
