If you can link the fall of democracy to misinformation being spread on their platform, genocide and mob murders, yes I’d say not all tech companies are that bad.
I think poor education, stagnation of living standards and rising inequality is a lot worse in that area than Facebook.
Granted, I think angrymob-media would be a much more fitting description than social-media, but it’s not like humanity wasn’t perfectly capable of making really shitty decisions long before the internet.
