Kylie Robison says her feed turned generic after brief YCSE early access

Kylie Robison says her X feed began filling with general-audience "midwit" posts after she spent 24 hours with YCSE, a product she had early access to alongside a few hundred other people.

Robison's post does not say what YCSE is, how the access worked, or how the feed change was measured, so the claim rests on her own account.
