I signed as well, and I believe we all should. As RickG pointed out, randomness is not the issue. RNG's have a much higher potential for abuse than do mechanical draw machines using ping-pong balls.
The way it works is, first, the lottery introduces a new game, usually a Pick-3 midday game. If they announce it at all, they tell us it will be drawn with an RNG, but they don't bother to give us any details, such as the manufacturer, or how they determine the odds of winning (in a Pick-3 game drawn with ping-pong balls, for example, I know my odds are 10x10x10 = 1,000 to 1 against me).
Later, they begin using their new toy in the evening games, but they don't tell anyone until after they've been doing it for a while. Then, they announce that they have done "extensive testing" to ensure a high degree of randomness. This "extensive testing" consists of the last few evenings' results, when they notice that their payouts are significantly lower than they were last week, but their sales have remained constant because no one knew they were using the computer to draw the numbers.
Next, they post a press release to their website announcing that all games will henceforth be drawn by the infernal machine, and advising residents that they will no longer be conducting live drawings on television due to lack of player interest, high air-time costs or "broadcasting conflicts." If you protest this policy, they'll tell you that you can still watch a live drawing on site, provided you give them advance notice or make an appointment before showing up.
Now, everything is in place. Next thing you know, your property taxes are going up because there's no lottery money to pay for schools and roads. All the money the lottery generates is shoveled into your state's policemen's, firemen's and teachers' pension funds to make up the shortages created when your governor's minions emptied them (think very carefully before you tell me I'm wrong about this - it's true, and I have the proof).
I made the following point on another related thread, but I think it deserves repeating here: Your Lottery Director serves at the behest of the Governor who appointed him, and that of the Lottery Commission who employs him. A more effective campaign could be waged by writing directly to your state's governor. Flood his office and his mansion with postal and electronic protests against the introduction of any proposed computerized drawing methods in your state lottery. Remind him of how Arnold Swarzenegger attained his current position. Make it a point to mention that recall elections are not exclusive to California.
Also, don't count on any help from your Attorney General. Even though it's an elected position, it's his job to represent the interests of the state, not those of its residents. In addition, it's his (or her) job to defend any state official who's caught breaking the law, including the governor (again, I've verified this, so I know it's true).
If we work together, I think a very potent players' lobby could be organized here, one which could develop a powerful voice in Washington.
