You mean that some company that ran a poorly secured TeamCity instance and got hacked decided to try and shift the blame to JetBrains, knowing full well that a certain demographic will eat up anything vaguely of the form "Six Degrees of Kevin Russian"?
Yeah no. Most sensible people don't consider a connection as tenuous as "some company that got hacked had misconfigured a product made by a company with offices in country X" as a reasonable thing to make insinuations on.
It is somewhat hard to work with Russian security services after this statement: https://blog.jetbrains.com/blog/2022/03/11/jetbrains-stateme...
Update: technically, there are some corporate lawyers and accountants that are working on closing JetBrain's LLC in Russia. But we are talking about software engineers, aren't we?
Pretty sure GRU officer was typing that blog entry with one hand, keeping fingers on other hand crossed behind his back.
