As a user of Friendica for the last two years, I would have certainly agreed with you just a pair of weeks ago. Fortunately, the latest version of Friendica finally included the option to cache network channel data, at long last solving the problem of having to wait upwards of 30 seconds for the network tab to open. The "see more" option is an add-on for some reason, two in fact depending on which implementation you want to use, and either of them must be first enabled by the instance's administrator.
I also agree that there must be some way of making PeerTube natively compatible with subscriptions and "superchats", if we want YouTubers and livestreamers to be capable of using it as an actual replacement for their YT/Twitch channels. The only payment methods I've seen enabled for PeerTube as plug-ins are all cryptocurrency-based unfortunately.
