My favorite is that for ~8 years after they killed their theater movie showings service at movies.google.com, that subdomain still pointed to the deprecation notice. They finally must have noticed earlier this year, because it changed to a hacky redirect to https://www.google.com/search?q=movies and now much more sanely points to the Youtube movie storefront. (This drove me crazy for years because I'd always instinctively type in movies.google.com thinking it'd intuitively take me to the Play Store... I was so excited when it finally changed off the deprecation notice.)
