Crested budgies do have a shorter life, but they still have that life to live. I will never encourage the deliberate breeding of these birds, but unfortunately a heck of a lot of them do end up in breeding programs the produce the next generation.
Yes it can be uncomfortable and a hindrance, but if I was to have one I'd trim those crest feathers down once they're fully grown. They can look like that, but they don't have to live like that.
