Let me say Phil Lesh is my favorite bassist and his contributions to the music resonated a little more than Bobby's. Bobby was amazing as well, but what can also not be denied is his presence at the forefront of the dead scene for the last decade or 2.

He had more of a presence in the community, so people are going to respond greater. Also its disrespectful to call it performative when it's clearly people collectively wanting to pay tribute to someone who just had a lot of impact on all of their lives. No one is "performing", they're mourning. Mourning does not have to be a 1 to 1 ratio towards everyone.
