I've always found it ironic that people who distrust software from Mark Zuckerberg instead trust software from... 3 guys in a garage.

"Those 3 guys in a garage would never sell us out! They are paragons of virtue!"

"We shall trust 27 different sets of 3 to 10 guys in garages and ensure they never become large enough to blackmail a large percentage of the world's governments safe in the knowledge we can in fact arrest them for illegal bs" does have an appeal however.

It's more trusting something you can audit and control (e.g. open source) vs trusting something you cannot audit and control (e.g. proprietary service by BigTech).
