How about a tl;dw for people who can read?

There’s a website tool hosted on neocities that’s attempting to become a geocities revival.

The video is functionally an ad for the community and the associated Web building tools.

Another walled garden, right in line with Web 2.0, but with a 90s pastiche done up in HTML5. Reminds me a bit of the Vaporwave style that flared up in the mid-10s.

Another walled garden

Not sure if you meant it this way, but Walled garden usually means ‘Closed Platform’, like a way to trap users. But the video is encouraging the construction of websites that can easily be self-hosted, which is the opposite of a walled garden.

It’s claiming they can be self-hosted, certainly. But they’re also claiming this is some kind of “Web Revival”. Do you know anyone who is building neocities sites and self-hosting them, much less getting any meaningful amount of traffic on their self-hosted websites?
