doanwon,
As I view it, if there is a redirect, then I believe Neom could sue for infringement.
As I understand it, in order to avoid infringement, to change a campaign for a direct code you would either need to change the code itself (meaning that you would have to change the billboard itself), or you would need to save the old campaign to a new file and store it somewhere, and then link the new campaign to a generic URL that you originally embeded in the direct code.
Hope this is not too confusing, however, as I say, to my knowledge "direct" continues to be a more involved, more difficult, and less friendly process...not to mention that other applications exist where indirect carry unique advantages and where direct may not be capable of playing at all.
Of course RFID and NFC stand to influence the landscape even more.
Please do NOT take my word on any of this. Perform the necessary research.
Best,
BC
