Their knowledge of the facts is probably 100x better than yours or mine.
That does not prevent business interests from pursuing their goals
using lawyers and influencing lawmakers and bureaucrats.

I'd like to believe it's dead. But until L^2 declare they are backing
off, it is not dead. They still have recourse to the courts, and as
long as they do, this is not a dead issue. It remains dangerous grounds.

The real point is they hoodwinked the FCC into granting notional
approval for that band for ground transmission. That is what the FCC
should focus on.
Based on _some_ of the aviation GPS receivers of which I'm very
familiar, filtering could likely be retrofitted into them.
Certification would be expensive and the filtering _might_ impact the
tracking algorithms. That affects software. Re-certifying _that_ would
be very expensive.
When I left that co., we had over 5000 units of a single model installed
in commercial passenger aircraft (widebodies and down).
However, some of the later receivers, have much more compact designs,
and I would bet it would be challenging/impossible to integrate filters
without redesign of the front end. Many thousands already delivered and
installed.
JAVAD seems to be L^2 night in shining armor. But as we know, it's
serving their interests, not the community's.

Good way to put it. However, IIRC aviation GPS' are not certified to
block signals in the out of band area in question.

The US, unfortunately, does not work that way. That is both the US'
strength and occasional deep weakness.
