Jim,
Rather one works from their RV or feels they need to stream media so they can be entertained while in their RV, I am of the opinion they should not depend on, or expect a RV park to provide free unlimited high speed internet, especially in locations such as your RV park.
There is no such thing as 'free', somebody is paying for it. We all need to be responsible users/consumers of our resources. When the cost of 'free stuff' is placed upon the consumer, they quickly realize it requires management, or do without.
I'm sure this recent policy change by Starlink has frustrated you, but IMO, so many in the RV community have unrealistic expectations on what they should receive for free or at minimal cost at a RV park.
