I changed ISPs when moved from one city to another, no difference. Yes, there were several episodes when connecting required about half an hour of playing changing setting but eventually I could connect. Nowadays it seems that the government abandoned their efforts to block Tor traffic and mainly focused on blocking VPN and Telegram.
Don't know, I use tor every day in Russia. Without it Internet would be unusable. The only problem I see is how to get initial distribution since the tor site is blocked.
You mean in recent history? Because Finns were nazi allies during WWII and participated in Siege of Leningrad starving hundreds of thousands to death. They also organized network of concentration camps during the war.
Don't understand why you have been downvoted. Russian government have already attempted to push forward their root certificate for banking using Yandex browser, now this.
