Additional information
Do you own research, of course. It appears that this project was set out to bring Internet connectivity to new communities. In the grand scheme of things, this is part of Facebook’s strategy “we reached a billion users, how to reach the next billion?”. Hard it is to progress when there is a conflict of interest this large with branching side debates such as net neutrality.
The story did not end well with several companies and individuals criticizing the direction the project was taking, partners leaving, regulation being harsh. But that does not mean it is not serving users right today. I cannot speak for the persons using the current version of this project -as of May of 2021- but I hope they are well and that they can get the most out of it.
