In recent years, many lotteries have changed their websites to highlight new instant games, promotions, and large jackpots on the homepage instead of number games - often not even listing daily draw results on their homepage anymore; burying such data deep inside their site. Many lotteries treat traditional number games (pick 3, pick 4, in-state lotto, etc) as old, outdated product and not overly promoting them. And by extension, lack of support and understanding of what many numbers players desire.
PA Lottery redid their website a couple of years back, and it's mediocre for numbers players. It's not terrible, but degraded from what it was. Many lotteries are far worse - Ohio's lottery website abomination makes PA seem fantastic. Ohio requires scrolling right and left just to view daily draw results. Worse, just to view past recent results requires searching.
Expect the issue to get worse in many states. The trend looks bleak - most lottery website updates I see dial-up the glitz at the expense of functionality; less data readily available for numbers players. However, if enough players complain, that may help in states that still, at least to some extent, value numbers players ... it did in PA - they redid their homepage to display all results with just one click (not ideal, but a compromise) instead of clicking and scrolling all over the place, and restored the ability to search past winning numbers.
Bottom line, in my view, it's not a conspiracy, but rather many lotteries simply don't care about supporting a shrinking base of diehard traditional numbers players. They'd rather court players who play quickpick / don't analyze their number selections, and push their higher selling products, in particular, instant games, which in many states now generate over 50% of their gross lottery revenue.
