A lot of privacy based ones on there, too. Infact it's the entire point of that repo. Nobody says use all of them. And, it's ...a list. There is absolutely nothing misguided about degoogling. It's not using google products. No google workspaces -> cryptpad, nextcloud, self-hosting. E-mail alternatives -> proton, but again, self-hosting alternatives on that list. Firefox, with tons of firefox addons.
And I would say yes, eradicate Google use. And my reason: https://kagi.com/smallweb
Go check out some of these pages, then google a string with quotes from one of them that only that site would have "something that site would have"
It won't come up in the Google results because it buries it so deep, or doesn't even index it that it's ridiculous.
We can have privacy, and a better web.
