We should view Social Media as a systemic issue instead of a symptomatic one and tackle its root:
Overcoming the commercial and exploitative logic we applied to digitalization so far.
Making social media better and safer for eyeryone will be more sustainable for young people AND for democracy.

This is still really irritating me because the response to a rumor like this in 2026 shouldn’t be to write a “Users say” article. We should have the ability to audit or investigate such claims and we don’t, and that is due to failure by the United States Congress to pass basic transparency laws.
"Users say" -- I'm sorry, this is irresponsible. This seems more like infrastructure issuer than some coordinated topical block. Why is "some users think a thing" a story?
"Users express lost of trust in TikTok following ownership shift" is a different story.

One of the issues that has come up again and again in my reporting on misinformation and social media is the massive influence social media companies have on research in the field.
Last night a preprint dropped that tries to get at this with some numbers. My piece in @science.org (and 🧪🧵 coming):

Nearly a third of social media research has undisclosed ties to industry, preprint claims
Industry-linked studies were also more likely to focus on particular topics, suggesting these ties may be skewing the field

“While we cannot definitively show that industry funding in this area is redirecting attention from products to consumers, our results are consistent with this possibility.”
