Forced update Rambler ICQ

Yesterday (on someone else's computer, there was no time to explore) I saw the following picture: when launching Rambler-ICQ 5.0, a window appeared with a proposal to upgrade to 5.1 and there is no possibility to continue working without updating .

If it is massive, and not a glitch (?!) of a specific computer, then Rambler has a completely new style of marketing.
