If Teams Personal (bundled with Windows 11) was just rebranded as Messenger, would you be interested in using it?
I understand that the messaging app environment is kind of a headache, but if MS wanted to make it so Windows and other platforms have an iMessage competitor that is as simple to use on desktop as on mobile, regardless of the technology and features, would it be just as easy as to lean into your nostalgia-based branding?
I find that for most cases, the features in Teams Personal are more robust compared to those found on WhatsApp or similars. Having the Teams name is such a deter, as it communicates Work stuff to most people.
In my head it would be like, leave as is and just rename every mention of Teams to Messenger.
