They'll most likely need to offer relocation to devs that want it, as they might not be able to employ and/or pay Russian devs anymore due to sanctions.
Jetbrains is Czech. They have lots of Russian developers, but that is an internal matter to them. It won't affect you or my use of Jetbrains products, but it will likely affect how quickly new features and bug fixes are deployed.
Look at their blogs. Their key employees are predominantly Russian. Being incorporated in Czech republic doesn't mean squat if their employees work in Russia.
> A lot of it comes down to basic quality of many creative endeavors: starting is easy, and finishing is hard. You can start anything, but if you work for long enough eventually you arrive at this ugly middle place. The part of the journey where you start to notice all the warts and imperfections of what you're making, when your limits start to show themselves, when the picture of the thing in your mind starts to diverge from what you're realistically capable of doing. Seeing that, knowing that it was you who created all of that "crap," and _still_ pushing through it to get to the flawed, imperfect, compromised final product, THAT is tough.
