There are many options where such links are a reasonable option. I'm okay to receive such a link to validate my e-mail for an account creation, or to unsubscribe from a mailing list at a place I don't have an account at, or to display an order status page at a shop where I ordered as a guest without creating an accoung.
But using them as the only option to login is really, really annoying. Mails can get trapped in spam filters, delayed by intermediate server overload or spam filters that sometimes take 10 minutes, servers doing graylisting... Plus all the other annoyances listed in the article (e.g. multi-device users, in-app browsers). At the very least, support passkeys if you really don't want to store (hashed) passwords. And no, SMS is not an alternative: I was several times barred from logging in to a service because SMS wasn't properly working (can happen easily while roaming abroad).
