I do think they will essentially die. They will morph into completely different websites, but I think they will be around for a long time, and I think their userbase won’t shrink even a bit.
Big websites are slowly adopting the facebook model: All the content is hidden and requires you login to view it. Creating an account requires some sort of personally identifying information like a phone number, photo of ID, mailing address, etc.
The old model simply turned out to be unprofitable. It was always done under the motto of “bring the people and the money will come” and so they made it as easy as possible to build up a large user base, but it turns out that motto is false on the internet, and investors have finally realized it. There is no point in having a massive user base if they don’t actually generate a profit for you. Anonymous internet users do not do this. They are indistinguishable from bots. If they don’t use adblock, they don’t click on ads. They don’t donate money. Yet they use up the majority of the server resources.
It used to be that you at least needed anonymous users to generate content for you, but (in part thanks to facebok) non-anonymous usage of the internet has become normalized. If anything the best content will come from someone who has their real name, and profile picture attached to the content they submit. The anonymous nobody is much less likely to post anything valuable.
I think the internet as we know it is dead, and tbh I don’t even blame big corporations for this. I blame mass tech illiteracy, and people’s willingness to sacrifice their privacy for some dopamine hits.
So, you’re blaming the victims? Not the billion dollar corporations, leveraging their immense power and wealth to drain as much value out everything they touch just to discard what remains the second it’s not creating enough money for them? Instead you blame the tech illiterate, that never had a chance? The poor and exploited, caught in the hamster wheel of capitalism barely able to plan until the next pay check?
