I assume they are launching this due to the recent news about WebKit removing support for progressive web apps (PWAs) in the future. This is also probably a move to compete directly with apps like Slack that already have desktop applications.<p>I would be really enthusiastic about this and install it everywhere if I was a Facebook Workplace customer, but I don't see the appeal from a consumer standpoint. There's a lot of potential for undetected data collection that can be done with a desktop app with permission to access video and microphone. I guess you could say the same about Slack and Microsoft Teams, but they have a better reputation for how they handle data they collect from their customers.<p>Ignoring the privacy issues, the consumer market for Facebook Messenger has already installed it on their mobile phones and get notifications there.
