I think most people around here don't know that they're edible and anyway that fruit is somewhat of a hassle to pick and prepare, but anyway once they're ripe they fall on the sidewalk and on cars, staining everything red, making the sidewalks slippery and leaving seeds behind. And there's no wild life to speak of, maybe some rats but not many, and birds don't seem to eat the fallen fruit. Wasps do, but it's not a positive point.

There's no soil (except a ~1m² square around each tree) because it's just a street in the city so although I don't find them a bother and I can pick a fruit from time to time while walking, I can well understand why people who live in this street would complain about it.

I can't understand what went through the mind of people who chose to plant these trees here. I think it's almost as bad as if those were mulberry trees (relative to staining power).

But it's just a remark on how fruit trees can be annoying to some people, for my part I used to live in another city where I was able to pick blackberries and raspberries on my way to work or to the supermarket, sometimes pears, and it was great. And in autumn I pick chestnuts here. Not too often because of PFAS pollution.

In many places, people worry about bugs and rats eating them, and the ones that don't get eaten start to rot and grow moldy. Generally just things people don't like in a dense city.

Any rotting fruit that falls on the ground will attract many animals and bugs. Lots of flies and wasps, as well as bigger animals like rats or raccoons. Depends on the city for the specific animal, but seems like there are plenty of animals in big cities (at least here in the US) - NYC famously has rats, for example.
