WhatsApp to launch third-party chat integration in Europe soon

What's everyone's opinion on this? Is it a good or bad thing? It's good, people can ditch WhatsApp and might be easier to convince people to leave it behind altogether. Bad - I can't imagine that meta do anything without something being in it for them.

Could this potentially help meta scrape information from other messengers?

Could the likes of signal make it optional for the user, whether or not they want to be able to chat across the different messengers..
