Not seeing the issue here. The original was played out after the first year.
Part of it is because of the blackwashing accusations, which is ridiculous but after the shitshow that has been the BLM coup of 2020, I can see why people are getting knee-jerk autistic and upset at seeing blacks in commercials and being shoehorned into media and Whites removed from them or demonized.
Sad part is, I knew this would happen once BLM went on their months-long rampage and now the Woke Left's complaints of "Minorities existing in media is seen as inherently political" is actually starting to come true.
Just like the Religious Right before them, the Woke Left caused a self-fulfilling prophecy with this where people seeing blacks and "queers" (AKA troons, lesbians, and "non-binary" freaks) in a work at all is being seen as political propaganda and is met with a negative backlash. The backlash itself is autistic as fuck, but it didn't come out of nowhere
Another part of it is because that specific ad has become an icon and it's one of those things everyone just expects during this time of year, even if it's become played out. Same logic as to why people got upset over Charlie Brown nearly being taken off the air this year or how so many people still tune in to see the annual Treehouse of Horror even if they haven't watched The Simpsons regularly since the mid-2000's.
We live in such a consumerist society that people get mad when an ad gets changed.
The Hershey's Christmas Bells ad is one of those mainstays in American pop culture that is ingrained in so many people's memories, it's one of the few cases where getting upset isn't consoomer BS simply because it's been in the public consciousness since 1990.
It's sort of like how The Wizard of Oz would always air at least once a year, usually around Easter or Thanksgiving or the previously mentioned Charlie Brown specials and Treehouse of Horror
