I don't get what the purpose of that is for. I know everyone can use their own cache server, but that's just a form of vendor lock-in, as relays are much more ubiquitous and this thing is a solution in search of a problem.

Here's an example. I haven't dug into their various codebases deep enough to know if this is only cache server or also client, but checkout the image linked on Nostrudel

noStrudel

A simple nostr web client focused on exploring nostr

And on Primal:

Silberengel

(a community relay) and (a document relay), from #GitCitadel, are two of the Top-30 liveliest #relays, now. No spam, no porn, no scammers. Just re...

Same event, but different image files. Makes it look like I use their media server, but I didn't. I used Nostr.build.

I see. So, they're taking users notes and recreating there own version in an attempt to create their own walled garden of misinformation as a means to gather user data and create false narratives about the level of progress (or lack there of) that they've made. Am I understanding this correctly?
