Hi Josh, I know I am literally nothing, just a simple citizen of western Europe, but I allow myself to say that your answer is not enough.
Recent days have seen unprecedented decisions made by all kinds of countries and major institutions regarding Russia.
I hope you will understand that this situation is different from your previous experience and that you should not let Ukrainians do this war alone.
Please consider doing something unprecedented too, with the power of your organization.
I’m sure there are smart and fully legal actions you can take with Let’s Encrypt, that would help adding pressure and marginalize Russia.
