Well, I think they're talking about tools like tensor flow.
Personally I dont consider open source codebases that don't come with services embedded as services, so things like Blink or AOSP that are made by google are fine, so long as they don't interact with google in any way or incorporate patterns that lead you into their funnel. They're FOSS code, not services, you might as well be running a fork, it doesn't really matter who makes them. I do use some software that is forked from google upstream code that removes these sorts of things, but I go to great lengths to make sure even simple things like using 8.8.8.8 are not occurring.
