Those are the only feats available for free. All other feats are published as part of a book not available for free. You don't have to purchase the whole book, though, you can buy just the feats from a book, or just a single specific feat, for a lower cost than the whole book (and if you come back and buy the rest of the book later, the purchase cost will count towards the cost of the whole book). If you have the print versions of the books, you can recreate the feat you want using the homebrew tools.
So, I can't pick any feats up for my Hobgoblin Bloodhunter except Firearms Specialist and Grappler, and I have no idea why.

The DM turned off content sharing and I had no idea that those two were the only free ones. Thank you!
