+  Privacy issues:
+  \begin{itemize}
+    \item Background requests to Google during build and run.
+    \item Depends on Google services for several features (e.g. Safe Browsing).
+    \item Limited privacy controls.
+  \end{itemize}
+  \bigskip
+  Freedom issues:
+  \begin{itemize}
+    \item Pre-built binaries throughout the code base.
+    \item Missing license in some source files.
+  \end{itemize}

+    \item Bromite: can build WebView; only focused on privacy and ad blocking
+    \item Debian: replaces pre-builts with system libs; Google services not removed
