- not a lawyer here -

I'd immediately remove every reference to linkedin -anywhere- and hard-block their domain in the code. Only after, I'd probably seek a release from the injunction.

Perhaps you should involve a lawyer, but if you won't, then limit yourself to a brief matter of fact explanation of what you've changed, focusing especially on the block in the source code. Do not address their points yourself. Refrain from any commentary, apologies, admissions.

I wouldn't go any further without a lawyer.
