good luck ranking in google and explaining your self to your md when your major publishing site takes 20 seconds to load I wont mention any names but I know of two cases of this.

The jQuery library is 45k, half that if gzipped. If it's taking 20 seconds to load, your birds are too slow.[1]

if it takes 20 seconds to load, you have bigger problems than jquery.

From experience where there is jquery there is normally at least a dozen other js files cut n pasted at random along with a similar number of css files with no thought to efficiency - hell most sites I se they can't even optimised the godamm images using Photoshop properly.

"JQuery is bad because some people who use it do unrelated things wrong"? Should I stop driving because some other people who use cars happen to cheat on their taxes?
