You "know" things that you're being told by Kremlin. You cannot believe even one thing Kremlin tells you. I am reading the socials - things on the ground, people who are experts in their fields reporting on stuff.
Example: all stores are switching from paper receipts to electronic only. Why? Because Finns closed the borders and all paper tape came from them.
Example: Sankt Peterburg can get VERY cold in the winter. They, and other regions in Russia, have very extensive and elaborate and expensive to maintain central heating systems. One tiny detail - in order for the pipes not to erode very quickly, hydrazine is used. Russia produces very little of that, most was imported from abroad, these imports have stopped. It is projected that failures of the central heating systems will start mid-winter next year.
Example: Russians cannot produce white smooth paper stock because the chemicals for that come from abroad. Thus offices are conserving paper, and switching to brown rough paper stock, which will abrade the printers quickly. Russia is about to cancel ЕГЭ - the SAT equivalents - this year, because of that.
etc. etc. etc. There are literally hundreds of such examples. Your Kremlin sources won't tell you about that.
