I think the opinion is that they exploit lack of laws in this area. Their business model is built to let people run essentially unlicensed hotels and rentals without those pesky restriction. They could easily prevent this but they have no interest in that. It is growth at all costs; who cares if "regular" people can't find apartments because people are buying them up as AirBNB properties. The regulations will eventually catch-up but it will take time.
