Its absolutely an issue that can be solved. The issue is that activpub is push based so their is no sing e source of truth. U could do a atproto style collector service that provides a search interface. U could also probably get a good but imperfect search by using the concept of n degrees of separation. Ie u search ur instance then search other instances who then search other instances.
Also some of the larger instances avoid the search issue by having a bot from their own instance subscribe to communities on other instances so that the content federates.
They have fuck all content. Fortunately both peertube and yt I regrate into pipepipe seemlessly so don’t even need a second app.
