No! No sorry if that wasn’t clear - they’re now considering adding “some” (quote -unquote) restrictions on walking … possibly related to the tee times you can go out; eg. no walkers before whatever AM, or before whatever maybe PM on weekends.
It’s a whole 'nutha discussion, of course, about playing ready golf regardless of walking or riding … but in my observations both on munis and here at this club it’s all too often two people in one cart who can negatively impact pace of play…
*With the important note that GOOD players know what to do! But GOOD players with GOOD golf course etiquette are the minority… 
For the riding carts, they have a different schedule of fees for 9 vs 18, weekday vs weekend, and there is a slightly lesser fee for using a push cart. On a busy day there they probably turn over the whole cart inventory twice, so yeah plenty of recurring revenue there.
That’s fine - the carts cost them something to lease and re-charge and maintain; plus there should be something of a “user fee” to maintain cart paths plus turf damage in those spots where they all roll over.
Anyway, again my disappointment here is that I was given the initial impression that they completely welcomed walkers … anytime … (sidebar: IMHO golf courses should encourage more people to walk) … so if there are changes to the current policy that just seems unfair.
