Sorry, that's a hard disagree from me and I think you couldn't be further off the mark.
Facebook's entire raison d'etre from day 1 is to take as much data from as many sources as possible, then use the most powerful computers, programmed by the brightest minds, to use that data to maximise their profit with no regard for what damage that may do to you or society at large - look at what Jonathan Haidt talks about wrt to mental health problems and social media.
They use the dirtiest psychological tactics to ensure that you never put down your phone and to ensure that you only see what they deem to have maximum engagement (whatever the f that means) and only put their hands up to any nefarious shit when a spotlight is on them for it.
I can understand Facebook wanting to clean up their image from a PR perspective but it's nothing to do with altruism or wanting to serve the public better... if they can make more money from looking like a decent bunch, they'll do it.
