What type of product was it? App, Service, or Hardware?
Service (Chrome Apps are listed as service, so let's list v2 extensions as service, too)

Killing of v2 extensions created a big controvercy. v2 extensions had features useful for adblockers. New manifest version (v3) is less capable in this field. Author of uBlock Origin wrote a big critique of v3 manifest: https://issues.chromium.org/issues/40598795#comment24 . Other critique:

Many products at "Killed by Google" are products killed because they are not really useful. Manifest v2 extensions seem to be opposite: it seems they are being killed exactly because they are useful! Manifest v2 extensions allow very advanced ad blocking, and Google doesn't like this!
