+			<h1>Topic introduction</h1>
+			<p>
+				There are many <b>threats to freedom</b> in the digital society.  They
+				include <b>nonfree software</b>, <b>massive surveillance</b>, and <b>censorship</b>.
+				<br><br>
+				Nonfree proprams are often designed to <b>restrict users</b>, <b>control
+				users</b> or <b>manipulate uesers</b>. The War on Sharing aims to stop users
+				from sharing copies of published works. Computers for voting make
+				<b>election results untrustworthy</b>.
+				<br><br>
+				Other threats come from use of web services, implemented by
+				companies that can impose <b>any conditions whatsoever</b>.
+				<br><br>
+				Finally, most internet activities (aside from those which existed
+				before 2000) are precarious, <b>dependent on permission from one company</b>.
+				<br><br>
+				All of these threats originate more or less in the use of nonfree
+				software. That is why free software is the first battle in
+				the <b>liberation of the digital society</b>.
