Because it all stems from a rumor that Disney's policy and procedure for the cards might be changing, and we are discussing the pros and cons of the current system, how it could be improved, and the effect changing the system could have. IE discussing. (ignoring the latest argument about race)
I'd like to add an update that the rumor that Disney may be changing current GAC card policys, look, and procedures is for sure true (if it hasn't already be stated). GAC cards WILL be changing in some form in the next few years. In addition to data being collected at attractions, a special committee has been formed to discuss how to fix the problem of abuse. Things being talked about, but not necessarily all be implemented are:
-Color change of the cards
-Larger stamps
-Legal fine print (Not for Resale. Non-Transferable.)
-Stricter enforcement of the 6 person rule.
-Requiring guests to visit guest relations each visit.
-Limit the amount of times it can be used at a given attraction. (No back to back to back use.)
-Possible MyMagic+ integration/Internal database of guests receiving cards (although cards are said to not go away right away)*
-Working with attractions to give out "return times" rather than "immediate access" for those needing an alternate entrance.
-Less contradiction in multiple stamps given / more education on proper stamps to give
-Stricter enforcement of card holder must be present AND riding the attraction to use the card
-Continual upgrades and refurbishments to attractions to make all attractions accessible resulting in no need for an alternative entrance for limited mobility or wheelchair parties.
*One thing about connecting GAC card information to MyMagic+ is that Disney now has medical information collected and stored with a guest name which is against the law unless they are a healthcare provider.
All this comes straight from the source. Nothing has been set in stone, but they do know abuse, reselling, and blogs posting on how to cheat the system all exist. They are not happy and want it to stop, but have to be careful how they still provide the service to those who need it and also protect themselves from legal trouble as well. Not sure if any of this is new, but it does seem to align with some posts on this topic.
