Technology doesn't exist in its own bubble isolated from society, politics, and economy. Changes in mainstream OSs and mainstreaming privacy concerns are absolutely the result of social, political, and economic change.
Keep in mind the companies involved in these technological changes make up a huge portion of our economy, and their users affected by their app store changes, for example, touch every sector. These changes come due to social pressure--these companies aren't doing this out of the goodness of their heart. And particularly with regards to Facebook, political pressure is being placed on them to self-regulate with regard to user data to avoid government regulation.
I am not accusing you of being anti-leaking (or pro-leaking), but it does sound like you've fallen for an anti-leaking narrative here.
