Criticism
The PIN system has been subject to widespread hacking. Without encryption, the system was easily circumvented by set-top boxes that are able to access individual videostreams when individual stream PIDs are entered. More recently, the PIN algorithm itself was cracked, allowing others to access the service.
Another downfall is that because the application is MHEG generated, if the set-top box was switched off, access to these channels was lost. It is also stated on-screen before purchase that not all boxes are compatible. Another factor is that a few cheaper boxes do not have MHEG support at all, and therefore cannot access the service.

Famous quotes containing the word criticism:
“Parents sometimes feel that if they don’t criticize their child, their child will never learn. Criticism doesn’t make people want to change; it makes them defensive.”
—Laurence Steinberg (20th century)
“The greater the decrease in the social significance of an art form, the sharper the distinction between criticism and enjoyment by the public. The conventional is uncritically enjoyed, and the truly new is criticized with aversion.”
—Walter Benjamin (1892–1940)
“I hold with the old-fashioned criticism that Browning is not really a poet, that he has all the gifts but the one needful and the pearls without the string; rather one should say raw nuggets and rough diamonds.”
—Gerard Manley Hopkins (1844–1889)
