There are possible reasons for why grandparents might spoil their grandkids even when they weren't as indulgent as parents. First, they don't usually live with the kids, so they don't really have to think about the side effects that these excesses might have on the child. Second, disciplining a child is hard, and the grandparents might no longer have the energy to deal with the persistent requests and tantrums that the child might throw if their requests are denied as they did when they were parents. Third, there's a common belief that people become more sentimental and mellow out as they grow older, meaning that grandparents are more likely to go Cuteness Overload over their adorable grandkids than they would have as young(er) adults towards their children.

In fact, their excessive affection might put them in direct conflict with their now adult children, who might resent that their parents showed more care and affection to their kids than what they themselves had received. Alternatively, the parents might not appreciate that the grandparents broke their house rules by giving their children things they're not supposed to have or allowing them to do things they shouldn't.
