Advertising campaign from VELCOM on TUT.BY

I came to the site of the Belarusian search engine today and was a bit taken aback. The TUT.BY corporate identity has been replaced by the Velcom corporate identity. For the first seconds it even confused me. No, of course I saw the Google logos for the holidays, and the Yandex search box. In my opinion, the owners of tut.by went too far.
At first I thought Velcom bought out tut.by, then it turned out that Velcom had been in the market of Belarus for 10 years.
By the way, favicon is not changed. (I think consciously).
