For every non-satisfactory "recipe" or "review" search, I can see people just forgetting about how they couldn't find what they wanted and since the "wins" of casual searches still overshadows "losses" of specific searches.
I'm not sure if this tracks, but outside of tech industry people, and friends who just Google everything as "my search + reddit", I haven't heard many complaints.
I use them all the time for work. !mdn for MDN, !dnab for .NET, !npm for NPM, !py3 for Python3 docs, !debman for Debian Manpages, !w for Wikipedia, !a for Amazon, !g for Google when you really need it.
I'm not affiliated with DDG; I just really, really love it.
Just look at that list of bangs you provided. It's a techie/dev's wet dream of sources. Not one of them is something somebody's mom is going to give one iota of a concern about.
It's a bit using the a particular search engine from your browser.
It's the enshitification of the entire internet, not just Google unfortunately.
