Looking at the table from 10th Gen, I believe it is misleading, at least in relation to Edmunds. I worked there, and Oracle (which was the source of truth) was replaced by PostgreSQL.
Mongo did replace Oracle product but it was Oracle's Coherence[1]. There wasn't a concern of Mongo loosing data, because the data could be reloaded again from Postgres if it got lost.
I also heard that they were considering replacing Mongo with Postgres as well, but I do not know where this went.
I think 10th Gen is just good at generating hype. The migration was not because Mongo was better but because Oracle was expensive and not that much better from Open Source alternatives.
