Yeah, this incident has started a storm of fear mongering and mis-information.
The vast majority of people commenting on exotic animals and bans don't realize that the bird they love, the 'domestic' dog they own or the plants they adore are actually all ... wait for it .... EXOTIC.
I made a comment about that on one article, and got called stupid for it!
I'm a biologist... "exotic", "invasive", and "native" are a very large part of my professional vocabulary.
Why keep a snake? Why keep any animal? Because you enjoy the animal, find something beautiful and fascinating about it, and it fits seamlessly into your lifestyle.
