IMHO it's not about Facebook directly making money from dating subscriptions, it's about getting back a chunk of the user engagement that Facebook has lost to dating apps, i.e. adding dating gives users another reason to stay in the Facebook app, helping Facebook stay relevant in their lives (and spend less time in other apps), plus of course increase session durations & other positive metrics which help company reports, and ultimately derive income by showing more ads to users, likely within the dating experience itself (eventually, if not intially).
