Have they ever implied this would apply to accrued causes of action though?

Would like a laywer to correct me if wrong, but these terms would only apply to any future events, not to the hacks that happened under the previous terms, for which they've already accrued the right to sue in a court (or whatever those terms said) regarding that hack, and 23andMe hasn't really implied otherwise just by updating its terms?

If they wanted that, they'd have to have explicitly included language like "by continuing to use our services after this notice, you covenant not to sue in court for any prior causes of action" or the like?
