[IANAL]<p>Paying a lawyer to draft a letter was deemed cheaper than trying to purchase the domain. That&#x27;s why they did that instead of offering to purchase it.<p>There&#x27;s an asymmetry of expense involved if they &quot;lawyer up&quot; and you just stonewall. To them, that&#x27;s the minimum value of the domain name. You can always &quot;lawyer up&quot; later to further increase their costs.<p>However, none of that matters. What matters is how much it is worth to you to keep the domain.<p>Good luck.
