Telegram played a big part in information sharing and collaboration during Covid. Being pseudonymous and having a pretty strong adversity to banning people or channels made it very popular.
The main issue I found is the opposing mainstream messages ironically became largely propaganda and mistruth based. You could find people who disbelieved the government and Pharma lies - however it was hard to believe anything in the chat, as it was full of angry people who would say anything to try counter the government’s lies.
And the people who should have been speaking out like doctors and nurses were threatened with their jobs. It’s hard to whistleblow in that case without being public about your identities.
Hopefully we can do better next time… it’s all pretty complex.
