Ads killed the web
Were you ever on Usenet?
Usenet failed to scale past the first million or so users. Present social media platforms number in the 100s of millions to billions.
I've argued for several other reasons in addition for which Usenet died:

Usenet was rad!
On an actually decentralized platform the radicals would still be there, but so would many other voices. Where users can't be banned for "wrongthink", communities must convince their audience with arguments or fear losing supporters. The chilling effect would be gone. A truly decentralized site would have plenty of communities the individual user doesn't agree with - just like in real life. And just like in real life users can deal with it by staying away.
This makes no sense and is completely wrong.
Can you give some examples?
dApps still on it's infancy, but it might come... Not sure if anyone will use it though, like the rest of the blockchains, lol
