A rule more analogous to Facebook's presumed position would be, "you can fix climate change, but you can't do anything that would reduce GDP per capita". Which in practice means that while some useful tools would be on the table, others would definitely not be.
Not really since facebook revenue is much more directly tied to engagnement than GDP ia to fossile fuel consumption.
To extens the metaphor, Facebook's "alternative energy" is non-advertising based revenue. I see zero efforts from facebook to move away from ad based revenue so there is zero chance that Facebook is going to make meaningful progress in changing.
