That's an editorial point, not a substantial one. Obviously requiring an application be submitted by an inconvenient and antiquated method that isn't used by the demographic in question is going to create friction and reduce the number of applications.
That this is expressed in a whimsical way (personally I liked the turn of phrase, but that's an issue of taste) might personally offend you but doesn't change the substance of the article.
It also has the effect of making the job posting seem fake, or like a scam, because who in their right mind would believe META, who has their own, in-house operated, online job application portal, would require a job application to be mailed in.
