Yes. Considering you cannot even say write/speak things without vindictive people using various methods like down voting or abusive language to stifle conversation and discussion and that has metastasized into things like "moderator" censorship and evil like shadow banning, hiding conversations ... not from being said, but controlling what adult humans are allowed to see ... all of which are directly and inherently treasonous for Americans to engage in due to their responsibility to uphold and defend the Constitution and the universal human right to free speech; then yes, it seems clear the internet, as the replacement of the public square AND books/newspapers, etc, as well as simply just universal freedom of expression and communication has made not just culture, but humanity worse off.

The "positivity ration" claims it takes 3:1 good things to overcome a bad thing. I would argue though that the nature of the evil that the internet facilitates is not just many bad things, but they also taint all the other things. We are in effect moving into a dynamic that is related to the pre-printing press era, when the ruling class had total control over information and the dissemination of it.

If you interrogate that aspect of history, you will clearly see the thread of that impulse throughout especially European history, even after the advent of the printing press. It was the same before the internet when things like state radio/TV stations and rules controlled what could be said and how. The internet briefly breached that containment from about '90 to '10s, until the speech control and tone policing or even the constant change and shift of language to dominate people.

It is naive, childish, and underdeveloped to simply take all the positives of the internet and ignore that there are many turds floating in that punch bowl.
