Generally Netflix makes shows in the same country in which it operates. This has a positive interaction between the country and the company, since the shows are more identifiable to the people who would watch them in that country. While the production in Russia probably would have to stop, there was no reason to turn off access to the existing and new customers. It had no measurable effect on Russia's actions or the outcome of the war. It was merely an attempt for Netflix to "be on the right side of history". Instead, it's shaping up to be Netflix "not being part of the future".
