You get what you...
You get what you pay for
Facebook, Youtube etc, are free or cheap enough, except for your attention and the information about yourself that you give up.
You get what you vote for
If you want something different, vote differently, if you do not like the choices, run for office yourself.
You get what you do nothing to stop
Evil happens when good people do nothing to stop it irrespective of what their opinions on what good and evil are.
If you do not like a company's behaviour:
Go to another company.
Create your own that out competes them that behaves as you see fit.
Buy them and change their behaviour.
Vote for legislators that create the regulations that enforce the behaviours you require.
Become a legislator and vote for the regulations that you require.
Do something that stops behaviours that you deem evil. Convince others to prevent evil from being done. Share your attempts with others.
You might want to create a manifesto in this case, just so people can understand your choices and the intent of your actions.
As has been said before, there are no easy options here.
There are plenty of easy to state wishes that are in a lot of cases, especially now extremely heartfelt.
But as has been observed many times before magical wish based thinking and requirements in the political/technological/social/environmental spaces serve no useful purpose.
It is only the choices that we make, the actions that we engage in that makes the world what we want. We live in a world full of other people that are choosing and acting as they see fit.
If these events prompt you to choose something or do something, then make your choice. Act.
