I totally agree with you. I just didn't get what RSA has to do with this lol
RSA is old (literally from 1977!), slow (because huge keys are required to make it non-trivial to brute force), and overall less secure than modern elliptic curve cryptography.
As I said though, I missed that they also have EdDSA and ECDSA keys when I skimmed the article during my lunch break. Since the RSA key is only for backwards compatibility it isn't an issue. Thank you for pointing that out to me.
