To add to other replies, the population is growing. Also, there might be less children proportionately (is "peak children" behind us in absolute numbers?), and survivability is higher, making these dumb games proportionally more visible. Of course, social media doesn't help. Firstly, for visibility. Secondly, everyone now has more connections to "dumb" friends, and a direct window into their lives. Lastly, current attention-focused recommendation algorithms often promote shocking, attention-grabing content, which makes such things both more visible, and likely to go viral. It also rewards sharing such content: more prominently displayed, it is more likely to "get likes", and fuels the pool of attention-grabbing posts the platform can use. Today's social media is full of perverse incentives, for a very marginal benefit to its users (even if that might not be obvious to them, as they are led to believe the contrary).
