If I make the path behind my home publicly accessible so people in our town can get where they’re going easier, then Amazon builds a warehouse in our town and starts driving their trucks through my path 24/7, are you going to tell me “well you made it public access, they have a right to it same as everyone”?
With the advent of trillion dollar corporations selling extremely powerful general purpose imitation as a service, the meaning of “public access” has substantially changed, potentially invalidating the original agreement.
