Disclaimer: I am only a young person in Germany, but used the 0.facebook.com service (facebook for free) here for almost 10 years.

Result: Yes, some internet is better than no internet.

Nowadays, where I stopped using facebook mostly, I just buy like the tiniest data package my provider supports, wait for it to throttle to 64kbps, and just use IRC, the web without JS, etc.

Will they be able to reply to this comment?

When internet.org is made available to these people, won't their usage or lack thereof signal their preference?

Which would you prefer, knowing what you know?
