@vbuendiar @ide In order for something to be forbidden there needs to be overwhelming evidence that the harm outweighs the benefits.
Importantly, the burden of proof lies on those that want to impose the ban!
If in doubt, there should be no restrictions. At least if you don't want to live in an authoritarian society.
We don't ban kitchen knives even though the causal connection to murder is pretty clear — incomparably so to quotes and timeline algorithms — and the harm caused is much higher.
Doing “harm” in social media — i.e. insulting someone — is a choice. Forcing people who do not make that choice not to use some posting feature is pretty much the definition of paternalism, i.e. removing people's agency and capacity do decide from themselves.
