The press is still free to cover whatever they want. Regulations, legislation, etc., are all public. They can comment and criticize to their hearts content.
Personally, I think the daily press briefing is a joke. It's purpose seem much less to inform the public than to give the White House press corps steady employment. Once a week seems fine to me, and maybe if there are major announcements. Otherwise....
What's the point?
The point of the article was to urge Donaldus Minimus
against the kind of micromanaged single-sided
press coverage His Excellency became too notorious for doing, and it's a sensible urging.
As for the daily press briefing, I wouldn't object to it being cut back to, say, twice a week. Once a week might
cause a little stink, and more than twice probably is a little too much, considering White House reporters
generally have access to the staff away from the daily press briefings. (I know, because I discovered it
while I worked in Washington in 1990-91 as a research consultant for the Heritage Foundation.) Brief
twice a week and, of course, make the exception for major announcements or activity, and that would seem
sensible enough.
