It seems the most likely explanation to me!

Edit: I will share what I think is a nice a little counterpoint story here, from a business that is clearly still interested in understanding. I sent Lego an email a while ago:
I'm just wondering if you're able to tell me what the
tune is that the Lego Primo musical camel plays in set
number 2007. It's a set from 1998. We have the camel and
it plays a nice tune, but no-one seems to know what it is!
They replied a day later: Thanks for getting in touch with us.
This is a really really really and I mean really interesting
question you got there for us. I have checked with all the
resources I have and come to a possible conclusion.
The Musical Camel – which in Denmark actually is called
‘PRIMO Dromedar'. 1st theory is that, One DUPLO-designer
says that the melody was composed by the designer that
created the camel but no one remembers the name who created
the Musical Camel. Another thing is, one of the engineer once
had a musical box that had the same melody but he is no
longer with us anymore and cannot provide us the answer.
I am so sorry that, at the end of the day I cannot provide
you with any name to the title. But I hope the facts can
make a good story for you to tell your friends.

We never worked it out.
I offered to provide some expert help on a set they were designing once and they immediately put me in direct contact with the designer in Billund. No bureaucracy.
Why can't more companies be this good? I've been trying for years to get into one Google account of mine :(
TV licensing on the other hand is "evil". They are in the business of collecting a tax that many people see as unfair, and prosecute those who don't pay. Even if their actions are fully justified, they won't make your life better, it is simply not their job. Even if they are genuinely nice in their communication, it won't change the fact that their are after your money and have to be forceful sometimes, and everything will be seen through these lens, so they might just as well assume their evilness.
I do realise that is not the case in the post, where it's probably even simpler to print the same message on every letter vs. only on some. And your point is of course well made in general.
Businesses are nice because they have to compete for customers, and that is easier if you're viewed as nice.
TV Licensing is a monopoly, they can have the worst customer service on earth, and that won't affect their revenue by much. There's just nowhere else to switch to.
This is also the reason why many government / publicly-run systems are so unfriendly and have such terrible UX. It's not like you can apply for benefits somewhere else (and the government would actually be very happy if you could!) , so nobody cares if the application is fifty pages and requires you to put in the same personal details 5 times.
To add insult to injury, there are no shareholders that demand the metrics to go up, so nobody has any incentive to optimize anything.
It fits the states' identities, New York is (somewhat exaggerating) a kafkaesque dystopia that wants to be in all of your business and have absolute control over everything you do, while New Hampshire's state motto is "Live Free or Die".

It appears to be used or sampled in a couple of songs (by Anna Maria Jopek and Boozehounds), but these date in the 2000s so can't have come into the camel from then I suppose!
