Piling on to the google alternatives heap: https://searx.space/
You can pick a public instance of searxng and choose which engines it queries by going to the setting cog, then Engines. A few of these public instances I’ve checked out have only google enabled, though, so you really do need to check the settings.
If you want to add a searxng instance as your default engine and your browser doesn’t automatically do it, the URL for that is: https://<searxng_url>/search?q=%s
I have to add this manually for things like ironfox/firefox mobile.
I feel like a lot of it is from new-ish users excited to talk about it and in the process of forming often prematurely strong opinions on this versus that within Linux. After 15 years of daily driving Linux desktop environments i settled on the one that gave me the least fuss and havent given it a second thought since. I suspect there are many with a similar story, but it’s a boring conversation start if people are looking to debate it.
