Having been acquired by facebook, its a pretty accurate read.

If they land in the right org, they'll be allowed to maintain the open version (see https://www.mapillary.com/) However that's a rare outcome.

They'll be dumped in some org, and then bit by bit told that they can't do what they were doing before and now need to "forge alignment" or some other bullshit by posting on workplace.

They will need to deliver impact, But, as there are 3 other teams trying to do the same thing as you, you'll either be used as a battering ram by your org to smash the competition, or offered up as meat to save headcount.
