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:
“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)
“In criticism I will be bold, and as sternly, absolutely just with friend and foe. From this purpose nothing shall turn me.”
—Edgar Allan Poe (1809–1845)
“I consider criticism merely a preliminary excitement, a statement of things a writer has to clear up in his own head sometime or other, probably antecedent to writing; of no value unless it come to fruit in the created work later.”
—Ezra Pound (1885–1972)
