I hope that I'm wrong here and there is evidence of actual bots, but as far as I can tell you're making this judgement based on the fact the people signing the RMS support letter have Russian sounding names. First off, yes I don't doubt that the totalitarian oppressive and oppressive governments are using this type of technique, in fact they are probably using it a lot because it is highly effective. However, it seems exceedingly unlikely that they have any interest in a spat in an, on the whole, insignificant professional organization.

I think it is worth reevaluating your opinion, as understanding the other side of an argument is useful and helps us understand the world better. Generalising, a bit in my experience Russians tend to be slightly technocratic valuing pragmatism over ideology, which seems natural considering that it was beaten out of them by a series of absolutist despots.

Still their opinions are valid even if most people in Europe and the US, no matter their political beliefs, will consider RMS to have perjured himself as an ideological leader to the extent that trust can not be mended, and consequently must resign.
