Overview
- The Italian virologist announced on Oct. 29 that future written science communication will shift to Substack behind a paywall instead of being posted freely on Facebook or X.
- He cited years of insults and threats that also reached his family as a primary reason to step back from open social channels.
- He also objected to opaque algorithmic distribution of his posts and to artificial intelligence systems training on his freely shared work without compensation.
- Access will cost under €2 per month with a credit card required, a low fee intended to deter abusive accounts and cover transaction costs.
- He set a six-month trial with a minimum-subscriber target and said he will close the Substack before summer if it is not met, while continuing television outreach on Che Tempo Che Fa.
