Not all people been upset about the action he made from the past since its truly understandable because no one can predict the future and for sure at that time its easy to get those BTC that's why he made that deal. Also for sure maybe there are other more than that undocumented and for sure they also didn't regret what they do from the past because its part of life where they spend what they think right for them at that time.
Well, Laszlo actually did come back after a few years and explained his actions. He did not do this to make a big gesture or to make a political statement.. he basically had a small daughter that was crazy about Pizza.... and he wanted to buy the 2 x Pizzas with his bitcoins to see if it can be done, because he wanted to see his daughter rubbing it all over her face.
He never even considered that the price of a Bitcoin will go up to $60 000 per coin. He thought it was the latest craze and that it will blow over in a few months.
He still says that he does not regret anything that he did and that he got a lot more out of that, than the money it is worth now. (How do you buy the title of being a legend in millions of people's eyes and even a day dedicated to your actions)
