Episode notes
How Plaintiffs Went Around Section 230
- Kaylee's win did not pierce Section 230 directly; it reframed Meta and YouTube as products whose design features can cause harm.
- Erin Mulvaney says the case targeted algorithms, infinite scroll, and notifications instead of user-posted content.
Kaylee's Heavy Social Media Use Became Trial Evidence
- Kaylee used YouTube and Instagram heavily from early childhood, and her lawyers tied that use to worsening depression, body dysmorphia, and self-harm thoughts.
- Jessica Mendoza says Kaylee watched YouTube at six, uploaded 200-plus videos before 10, and once spent 16 hours on Instagram.
The Case Cast Social Apps As Defective Products
- The plaintiff's team treated social platforms like any consumer product and argued defective design can trigger ordinary product-liability rules.
- Erin Mulvaney compares it to suing a carmaker over airbags or a toy company over lead paint.
