This has been going on for years. A large part of it, at least in my experience, is people who object to scooters being parked in a manner that blocks pedestrian or cyclist paths.

One particularly funny incident I'm aware of involved an acquaintance who was overcharged by a scooter company and couldn't get a resolution via support. Being a 'frontier justice' sort of fellow, he rounded up 20+ scooters and chucked them all into a pond in the name of justice.
