In addition to the other points made by others about sharing staff... At their respective peaks Meta had around 12x the staff of peak Twitter despite not having 10x the user base (that said Meta towers heavily over Twitter in users and monthly accesses.) Even today Meta still has more than 10x the staff of peak Twitter. If anything you're highlighting that at ~7,500 staff Twitter was probably too thinly run.
