Facebook had a high-profile setback when its Free Basics mobile connectivity program got blocked in India earlier this month over net neutrality issues, but its CEO Mark Zuckerberg is adamant — even upbeat — about the social network continuing to look for other ways to provide services to more users anyway, including laser transmissions from light aircraft and some 10,000 old school hotspots.

"That's disappointing for the mission and a major setback," Zuckerberg said of the India decision, "but every country is different."

Speaking at a fireside chat at the Mobile World Congress in Barcelona mired with a lot of audio issues, the conversation covered a range of topics from Facebook's connectivity mission, to virtual reality, 5G and its sucky start in mobile, Zuckerberg also shrugged off the criticism that the company has had about what its real motives are for Internet.org, the umbrella organization that is behind all of these projects. Some believe Facebook's interest in connectivity is less humanitarian and more opportunistic — a way of building its advertising network.
