BS as Pprune Radar says, NATS are clean on this. They did initially raise objections to the release of the data last November but later withdrew them. NATS do not object to release of the data, it is the CAA ADAP1 who are refusing to release it per my earlier post.

There are too many NOTAMs if you don't use the site properly. Cranes within ATZ's (and they are generally only listed if they are within ATZ's) are only included in a Narrow Route brief if they are at your arrival departure or alternate aerodromes.
The whole point of the AIS site tools is to filter the output down to that which is relevant to your intended flight. If you take the trouble to learn how to use the tools you can get good results. If you don't then the system fails safe, i.e. it gives you everything.
There will inevitably be NOTAM which many will feel irrelevant. Most are now properly coded but a few still get through, for example is it essential for aircrew to know about changes in callsigns of medevac helicopters? (that was a recent one)
The FIR VFR briefs are intended for printing out and to go on the noticeboard. They are sorted geographically but unfortunately our group's recommendation was not followed and the sort is also subdivided into type of NOTAM, not something we asked for.
You can find info on applicability of the various briefs
here, togther with alternate sources.
Half an hour on the AIS site with a printout of the FAQ and PIB Help documents should make anyone an expert.
Two things appear to be coming through loud and clear from this discussion:.
1. Many airfields do not display an FIR brief on the noticeboard.
2. Too many pilots are aviating unbriefed and infringing.
