I had the same email, there aren't many petitions that get to the debate stage so yes, it's a small win. Gambling addiction has all been made so much worse by the pandemic and people being stuck at home. I'll bet that there are many people who've recently picked up a gambling habit, who might not have done so otherwise.
Those disingenuous ads on TV that we have to endure now - "take a break, don't gamble all day" etc etc. The apps are designed to lure you in and keep you there without taking a break!
