I feel like it'd end up like Jellyfin vs Emby, it's an open project and source is available

My Guess is they will push hard into the hardware side with more of a "Managed service" offering as well. A Proposition of the benefits of this open source ultra compatible ecosystem without the drawback of running your own server and backups etc etc.

I know I run HA at home and its generally good, but ive not benefitted from historical data b/c I re-build it from scratch semi regularly and cant be bothered to handle backups properly :)

According to their press release: ""We've done this to create a bulwark against surveillance capitalism, the risk of buyout, and open-source projects becoming abandonware," the Open Home Foundation states in a press release. "To an extent, this protection extends even against our future selves—so that smart home users can continue to benefit for years, if not decades. No matter what comes."

As we've seen with 'OpenAI' there's never a guarantee, but I applaud this step.

You mean ClosedAI, stop saying their name wrong.
