Remove hyperlink but keep text?

this should work:

$('a[title="Show Profile"]').contents().unwrap();

Here a Fiddle with the proof.

Vanilla JavaScript way (instead of jQuery) to remove hyperlink but keep text:

const links = document.querySelectorAll('a[title="Show Profile"]')

links.forEach(link => {
    const el = document.createElement('span')
    el.textContent = link.textContent
    link.parentNode.replaceChild(el, link)
})
