The serial number

A short and small investigation, the findings of which are not very significant, but amusing.
There is a fairly well-known framework for building dynamic maps. It is used in many places, including by Yandex, something like this .
If you dig a little deeper, you can get the serial number of the product.
And the most inquisitive can learn that this serial number uses not only Yandex .
It can be calculated that Yandex is serious enough not to use broken keys in public projects. But the following facts are a little alarming:
1. The site www.astronomy2009.org also can not be called frivolous
2. The Yandex site itself is not in the list of “consumers” of the serial number.
In general, someone stole someone. Who does not know who, my investigation is over.
UPD: I did not notice the elephant, Yandex is indeed a client of AmMap. By the way, I tried the serial on the demo version - it works for itself.
