If you actually think there’s some dude at Niantic sitting at his computer changing code api’s or algorithms just to prevent you from getting Riolu/Shinx specifically, you think way too highly of yourself. The 10k eggs are full of “rare” Pokémon and there are so many possible hatches that RNG can quite easily screw you over.
And no, before you suggest it, skewing egg hatches based on the amount of money you spend on the game is a ridiculous concept to program into a game, not because it’s hard, but because WHY WOULD YOU SCREW PAYING PLAYERS BY SHOEHORNING THEM INTO A SUBSET OF EGG HATCHES?!?!
Get over it dude. Niantic does make blatant cash grabs all the time but this is just you losing your cool and projecting your frustration onto the “big bad corporation” that’s “out to get us all”
