Well, there was an Open Letter on change.org which was signed by over 1M people, its author was shortly arrested. Also, there were more than dozens open letters from various communites (IT included, 33K signatures). The only impact those open letters had is that now there is a new law in Russia which prohibits (up to 3 years in prison) any public calls to stop Russian army from doing what its are doing. This new law can (and will, in individual cases) be interpreted as "signing the open letter == call to stop a XXX == law violation".
