I’d expect modern cars to use proximity detection which means the fob only needs to be with you.
Like my Peguot has a fairly large fob, but it’s just in the pocket of my jacket. Never leaves it. I guess it’s a problem if you don’t have a semi permanent thing like a jacket you use every day though.
The article goes into the first point though.
Using those services on your behalf is, potentially (in a legal sense) use of your data. By providing some information to a third party, even if Firefox itself doesn’t itself use it. This may come from the fact that you don’t directly agree to terms with the third parties when you start using the browser, with safe browsing for example. So Firefox is in a sense using/sharing private information. And in the changing legal landscape this usage may fall under modern privacy laws, such as the one mentioned in the article.
I agree the old wording was bad, but I do see the reasoning behind the new one.
