On one hand, the scooters were a pain in the ass. They dumped scooters all over sidewalks blocking the way. People often rode them on sidewalks posing a danger to people walking.

On the other hand, it was a low-pollution way of getting around a city without needing a car, and people actually used the scooters. If we're going to keep the world from melting, there need to be fewer cars. Not just fewer internal-combustion cars, fewer cars in general. If we just replace gasoline engines with electric motors, it's not going to solve the climate crisis. Cars also just make cities awful to walk, bike or use a scooter in. So, even if they were all electric, it would be annoying.

Personally, I always liked the bike sharing options a lot more than the scooter options. Whenever I was a tourist in a city that had those bike share programs, that's always how I preferred to get around. You see a lot more, you can stop anywhere and take pictures, and when you're done you can just plug the bike into the nearest available bike storage stand. But, scooters could be part of the solution. There are probably people who would ride scooters who wouldn't use bikes, even e-bikes. If anything reduces the number of car journeys people take, it's probably a good thing.
