Sure. I'm a big fan of federation. However, I switched to Mastodon (the ActivityPub application) because I liked its style better than Twitter. Turning Mastodon into Twitter to attract a larger audience and placate the complainers isn't necessarily what everyone wants. Just my personal view on this. But it honestly doesn't bother me that much.
The signup/moderation issue feels somewhat similar. Yeah, it would be way more Twitter-like if signup defaulted to Mastodon.social and that mega-instance hired a content moderation team to rival a professional social media site. But that's not quite what I think is currently good about Mastodon and Fedi...
