We know virtually nothing about the situation. Pinball Rescue has done good things for a lot of people for a long time. They couldn't reach a deal with PPS and that sucks, but they aren't doing anything that can't be replicated or picked up by any other vendor. Laserific seems to have no issues working with PPS along with various other companies on Pinside that are making official products now.
IPB (as we knew it) is gone, and it appears it's going to take some time to find new suppliers willing to play the PPS game, which again can't be that bad as many vendors are already. I just can't wrap my head around some of these posts that are making wild and crazy assumptions so convinced they know exactly what's going on.
There will be less pinball parts out there for a while, but everyone seems to think that's PPS's fault, and it's not. It's because IPB doesn't exist and the transition is going to take time. If Pinball Rescue isn't the vendor to make those stickers and those plastics, then it'll be someone else. But not overnight.
I guess I'm saving my anger, and outrage, and boycott for the day PPS actually does something wrong or shitty. They paid the money, they have their way of doing things, adapt or move aside. In a few months, if at least some of this stuff isn't available again, lets break out the pitchforks. If there is demand there is money to be made, and if there is money to be made, the products will be there.
