Remote Legal Specialist interview questions

It was not really an interview, but the worst rejection letter I ever saw in my entire 21 years career. I quote: "I'd like to share with you a very important update - we've just closed this position with a candidate who proved to be perfect for the position. I'm talking about an internal candidate, that is, an employee of Remote, who applied to it and had - of course - the advantage of having the quality of their work, skills and experience totally clear to the team. As you can imagine, internal promotion and career progression is our preferred method of filling out a position. This means, of course, that we will be unable to consider you for this particular role but we would strongly encourage you to stay tuned (by periodically checking our careers page at _______) and apply as soon as you see a position that catches your attention and matches your skills." Thus a very condescending letter that serves no purpose. Am I supposed to feel happy that they picked the perfect candidate internally? Am I supposed to apply again in the future, if they prefer hiring internally? Horrible letter of rejection...
