While good advice in general, these sort of products are designed for professionals with 40 hours of exposure a week to hazardous materials. Vacuuming up small quantities on an infrequent basis isn't going to create an elevated risk.
Sadly, I know that a number more than zero of building companies will simply bury asbestos when they happen upon it, rather than paying through the nose for specialist disposal companies.
Do all companies follow these steps, no. Can they be held accountable for neglecting safety, yes. Being exposed to hazard materials like asbestos is gross negligence. Knowing that such a company exists doesn't means it's normal or common practice.
