This is pure FUD. They're still trying to block it, the latest three attempts happened this week. Two of them were done in the middle of the night as training exercise, maybe for 3-4 hours each, and the last one then happened in the middle of the day. All three broke large parts of the internet and were quickly reverted.
When something newsworthy happens in some region, all messengers get blocked in that region for days, Telegram included. They don't care about collateral damage to other websites then.
You're the one who is spreading FUD. Telegram was officially (legally) unblocked in 2020. There is 0 evidence there is an active force trying to block Telegram in Russia. Which is very busy blocking every non-russian platform btw. As you yourself pointed out, most likely the reason why TG was down is because of attempts to block other platforms.
And? I use TG everyday. I know about the times when TG is down. as YOUR OWN links show, usually it's not just telegram who is down, so it's clear it's mass block.
