Does Bluesky manipulate one’s feed or does it let it be based on the user’s subscriptions’ posts posted in reverse chronological order, filtered by the user’s preferences? Like Mastodon does?

Not only can you get reverse chronological feed, you can build your own feed with custom logic with a few clicks and share it with other people!

Bluesky lets you configure your feeds, or add new ones: https://bsky.app/feeds

Default Bluesky has the "Discover" feed and the "Following" feed. The "Discover" feed is the equivalent of the algorithmic "For you" feed in X, but you can always unpin it.

The "Following" feed is close to what you want I think.

Your “following” is reverse chronological.
