Where 2018 fits
Why 2018 is special
It gave people rights over data held about them and set fines proportional to global turnover. Its most visible consequence for most users is a consent banner on every website, which was not the intended outcome.

- Technology & computing
RFC 2018 specifies the TCP selective acknowledgement option. Without it a receiver can only report contiguous progress, so a single loss forces retransmission of everything sent after it.
- Law & regulation
GDPR granted access, correction and erasure rights and set penalties large enough to matter. What most people encounter is a consent dialogue on every site, which reflects how the industry chose to comply rather than what the regulation required.

Selective acknowledgement lets a receiver say precisely what arrived, so one loss no longer forces wholesale retransmission.
GDPR took effect five years after the Snowden disclosures, and both are part of the same shift in how personal data is treated legally and technically.
