Twitter icon upside-down
<p>If I use Twitter icon upside-down as my site favicon, will it be a copyright/trademark violation?</p>
<p>I have copywriting slogan &quot;Down with Twitter&quot; among others on my site.</p>

<blockquote>
<p>...will it be a copyright/trademark violation?</p>
</blockquote>
<p>You'll find out when Twitter threatens to sue, or does sue you. How much money do you have to defend yourself?</p>
<p>The court (judge or jury) will decide if your usage infringes and dilutes Twitter's business and trademark, or not. Or, if you claim usage of the upside down icon is a parody, the court will decide if indeed your usage could be viewed as a parody by the public.</p>
<p>You might win.</p>
