We already have an organisation that seems to model itself on the Masons. We call it TTA.
The Masons are secretive, and this has led to a lot of suspicion of them. But both my grandfathers were Masons, and the organisation is incredibly supportive of its members, their families, and their local communities. Take another look at your local Masonic Hall. You may be surprised how it bears a remarkable resemblance to Victorian Schools, Hospitals and churches in your area. That's probably because they were funded and built by the same people.
Since the Second World War the organisation seemed to get more involved in supporting its own members, but in the background, an awful lot of real help and support for the local community still takes place.
I have never been a mason, but my brother in law is, and he has been a builder all his life. He is very down to earth, incorruptible, and very supportive of anyone with a problem.
The TV programme undoubtedly is a PR exercise by a few Masonic activists, and is probably as true to life as your average police or hospital reality documentary. I.e it's bull excrement. But that's just a personal opinion.... 😀
