I don't want to speculate about their motives, but I've complained about them replacing my content with image links to their cache server or Highlighter or whatnot, and they don't care. They say it's necessary for the UX, but it actually makes the app slower because you can write immediately, but reads get fed through a long, tiny data funnel and fiddled with. It's why everyone thinks relays are slow. No, relays are really fast. Communication is nearly-instantaneous, in both directions. But, since so many people use Primal, everyone who "has tried Nostr" has used Primal, so they determine what everyone thinks Nostr is.
