Part of I feel like is that 10-15+ years ago, people only owned a couple of items with rechargable lithium batteries in them (if any at all!), and now people can have dozens. So the tiny chance of having one catching on fire is just multiplied by 10-20x just because there are many more of them around.
The other thing that was mentioned was that devices got thinner so there's a bit more chance of bending, squashing etc. stressing or puncturing the battery which can cause a fire.
And thirdly I think is cheap devices that don't have adequate protection against thermal issues etc., but that's mostly a risk during charging (that's where those hoverboard fire stories came from).
