I think it's not unimportant. In the past, Astronauts have been highly skilled people that trained their whole life for one goal, to get into space. It's a job and a calling.
Are these new people that go into space that? I would just call them space tourists, not astronauts. If they do not perform task during the flight, they're passengers, not crew.
It is great that the accessibility of space is getting better, but calling everyone that goes into space an astronaut would be, in my opinion, diminishing the achievement of the people that came before them and pushed this frontier.
These are not the explorers, these are the colonialists.
