I think there are multiple wins but one I see is that the liability falls on open source commercial entities, support services, and any services that handles PII but also if I am reading the law right there is mandatory disclosure so open source projects will essentially get free code audits, patches included thanks to the liability risk.
Unless I've terribly misinterpreted the text which is entirely plausible given a lack of sleep and a enough coffee to jump start a small star.
