I suppose a lot depends on how we define 'world' and 'open source'. Still, there is an argument to be had ( and what FSF advocates ) about benefits of open software. "Closed source" is absolutely a compelling reason and, from where I sit, companies and organizations across the globe have shown time and again that they simply cannot be trusted and will engage in 'goodwill withdrawal' when convenient.

<< Most of the planet is using some form of closed source web browser the top 3 being Chrome, Safari, or Edge.

Sadly, I personally believe popularity is a bad reason to advocate for technology. I kinda buy your argument that 'closed source' is not inherently bad ( edit: but it does require trust hence my first paragraph ).
