apt remove sudo

sudo is not installed on several distributions by default, so hardly surprising it’s not there or that you can remove it.

considering how huge FB still is.

FB is only huge because they’ve expanded all over the globe, even providing internet to developing nations to facilitate new user acquisition. In reality they’ve been bleeding the original Western users that signed up between '04-'10, and growth among new generations flatland a long time ago. There’s a reason Meta aggressively expanded to other ventures (or attempt to create platforms) like Instagram, Threads, what’s app, VR and metaverse. Metas only chance at sustainable growth and capturing young people is to build or buy platforms young people will use, because it ain’t Facebook.
