The "Chrome/Web vs Mastodon/Fediverse" isn't event correct, it should be "Chrome/Web vs Tusky/(Mastodon|Fediverse)", or "Twitter/Web vs Mastodon/Fediverse"?. Those things operate on a different level, they can't really be compared because they serve a different purpose.

Twitter users aren't joining the Fediverse, they're joining Mastodon. They rightly don't care about the Fediverse, they're just looking for a Twitter alternative, that's what Mastodon is. The Fediverse isn't tangible like Mastodon is. For the majority of users, that's an implementation detail.
