Server to client, client back to server. Each swing deposits frameworks, build tools, and mental models that never fully clear away. jQuery shipped in 2006 and still runs on nearly 78% of top websites.

The Microsoft antitrust playbook, repeated almost exactly. - **The Last Independent Engine Depends on Its Biggest Competitor to Survive** — [Source]() — Published 2026-04-15 Mozilla's finances hinge on Google's search deal.
