Not really. I can be reasonably sure that end-user applications I download for a desktop are limited in the damage they can do (even more so for iOS or Android)

Not really. I can be reasonably sure that end-user applications I download for a desktop are limited in the damage they can do (even more so for iOS or Android). This isn't something that happens often with programming libraries, but there's no inherent reason they can't be built in a way that they run in a rights-limited environment.
