less of a question of maturity (being self-sufficient, which Facebook and its employees clearly are), more of integrity

integrity implies that you are unified or "integrated" as a part of a stronger whole, and working towards the betterment of that whole

that you share certain core values and ethics with another group of people

in the past large companies might have been integrated and integral to a certain city, region, community, country, cause, etc. - or as you put it, "our democracy"

facebook, and most large tech companies, no longer have or need such ties towards individuals, communities, or countries

they pay their taxes in all different jurisdictions (or sometimes mostly just in ireland) and then are free to do as they like to their users who keep coming back for more screentime because they're addicted

facebook has no sense of care for the user, or a sense of being in it together as a relationship, nor is it really possible to have one at Facebook's scale

i wouldn't be surprised if Zuckerberg still considers the majority of Facebook's users "dumb fucks" and sheep to be monetized, an ethos that will inevitably trickle down through the company from the top

facebook's integrity is aligned with their customers, the advertisers, and that's about it

we can only hope that facebook employees are doing what they can to preserve their own integrity with their friends/family/community, and that this push is strong enough to shape the development of the platform for the better, instead of towards further addictive, attention-grabbing, echo chamber construction
