Drupal and Alfa Bank together

It turned out by accident that one of the Alfa-Bank sites was made on Drupal and even more - the order was made by the Artemy Lebedev Studio.
The site is this idea.alfabank.ru . The fact that this is Drupal is shown by an add-on for Firefox called Wappalyzer.
I think this is a clear indicator of the quality of Drupal and its relevance to the business.
