Billie Joe Armstrong, the lead singer of Green Day, spray-painted a green 'B' over the Oakland Athletics logo at Rogers Centre in Toronto during the band's 'Saviors' tour. This act, shared via Instagram, reflects Armstrong's shift in allegiance to the newly established Oakland Ballers after the A's announced their move to Las Vegas. The defacement was met with mixed reactions, with some praising Armstrong's boldness while others criticized his insensitivity towards political matters, as he recently faced backlash for displaying a mask of Donald Trump labeled 'Idiot' during a performance. It remains unclear if Armstrong will face any legal repercussions for his actions at the stadium. The Oakland Athletics have been a part of the Bay Area since 1968, and Armstrong's actions signify his discontent with the team's relocation plans. Green Day's concert, featuring the Smashing Pumpkins and Rancid, drew significant attention amid these developments.
