I'm confused about what you are trying to imply with your question.
Either you are making an argument for "Netflix/AirBnB are considered tech companies, so why not WeWork?". Or you are saying that Netflix/AirBnB aren't actually tech companies? Or are you implying that given enough time, WeWork would have become a tech company, despite its non-technical beginnings?
To compare AirBnB/Netflix to WeWork from a technology standpoint doesn't make any sense IMO.
