But a lot of things that agencies like Роскомнадзор do are simply because it made someone a quick buck somewhere down the line. Many of my friends/colleagues work for businesses run by old men who are more interested in 10,000 rubles now than 100,000 rubles in a week. The decisions that Роскомнадзор and other government entities makes rarely have much more of a thought process beyond a simple "well, we wanted X". When the Telegram ban came into effect and folks outside of Russia were flabbergasted by Russia's choice to just block major parts of AWS, people came up with the most outrageous of theories as to what was happening. The simple and more accurate truth was probably that whoever made the decision at Роскомнадзор to do the blocks neither thought about the implications of such a decision nor had the technical knowledge to really understand it, and those underneath this person likely didn't have the will or inspiration to care, hence why the block is so trivial to bypass (like all the other blocks)
Like with many countries, a lot of old political methodology has to die off before Russia can really step forward, and while that is happening, it's why projects like Tor are essential for providing unmitigated access, whether it is a malicious block (Telegram) or a senseless one. That so many US companies just have a straight up IP block on all things Russia doesn't help to advance the situation past this stage at all.
