I all for hosting things local. However…if we do fonts local then what is next, avatars? no more gravatars. Then what else will be hosted local……..not that I disagree with it per say. I removed Google Analytics long time ago. I never really used “log in with (facebook/twitter/disqus/etc”).

What else are we going to move from third-party product/service to local? Many of us have latest tweet/instagram/etc…on the sidebar.

So many plugins with freemius thing and other plugins asking for “data”.
How do I know they are not getting personally identifiable data?

Moving things locally can have bad “side effects”. Look at Gravatar…….one avatar loaded. Everything going local will mean you will have to upload an avatar for every site you go out there.
