No, corporations supported the BLM movement. The organization may have some marxists in it but the BLM movement has many chapters, some farther left than others. The founders had Marxist leanings but so what? So did unions back in the day. That doesn't make unions communist. At the end of the day though most people support BLM, who aren't marxists and those were the people being targeted by corporations. Even Wall Street executives took a knee, they're not marxists. They support corporate friendly politicians. Again, did Wall Street back Sanders or Warren? Nope, they backed Joe Biden in the primary.
And yes it's profit but honestly, I'd prefer that to having corporations be actively against minorities.
