I have said this many times in the past: SOCIAL SHARING on themes is completely wrong.

What if I switch to another theme? because I want one or the author abandoned it or whatever reason.

Those sharing tools will not be there on the new theme.

Right now to all my social media profiles, are on a text widget with old a href img src link. If the theme has it, and I change it then those links go.

I have never EVER kept a theme for over a year. Partially due to not being compatible with a WordPress version.

Doesn't JetPack have a sharing module?

Edit: All my social media icons are on my uploads folder and not on a plugin's folder.
