Everyone is using nginx and that was made by a Russian, does that mean we should stop using it?
This is why 'guilt by association' doesn't work with your 'point'.
What if the parent comment mentioned this instead:
Also WinRAR is a closed source Russian software.
To be fair so is AIMP.
To add to this, it may also be worth noting that Russian developers have contributed quite heavily to Linux, BSD, Microsoft Windows and Solaris. I can only assume also MacOS.
