MongoDB has been doing fsync by default for over a decade now .
And those that actually had tried it were aware that every client enabled fsync out of the box. So in fact the entire situation was seriously overblown.
But sure let irrational ideology affect your technology decisions. That will work out well.
Avoiding a database that has a proven historical record of disregarding data consistency and resorting to marketing gimmicks is "irrational ideology"?
Not everyone has time to review every single line of code in their tech stacks. Past reputation is important, and your replies here don't seem to be of much help to MongoDB's reputation as far as I can tell.
