Yes, but. I haven't used Microsoft groupware, but my impression is that like Google there's a bunch of multi-player value.

An office where everyone uses local software, that has no idea there is a network share, feels like the eternal conundrum today: it's potentially a Linux on the desktop win. But in the meantime most people would rather not need to manage individual desktops. Cross-machine multi-player experiences are increasingly table-stakes. It doesn't have to be the cloud per se, but it's been multiple decades now of open source competing for the desktop, and it's really been struggling to skate to where the puck's going. It hasn't been on desktop in a while.

A sidebar here, but I think this is what makes atproto so compelling to me. Posts like "A Social Filesystem" talk to how atproto is common glue, and it takes a little imagining, but it's absolutely a substrate that could be used for multiplayer office (via internal-only atproto networks, or upcoming ATproto Spaces). https://overreacted.io/a-social-filesystem/ https://news.ycombinator.com/item?id=46665839
