I think these examples are showing that the younger generational(18-35) have figured out and decided that the safety and health of their parents/grandparents are not of high concern.
The whole lockdown was intended to protect the older generation. Countries were willing to lose trillions of dollars in order to save hundreds of thousands if not millions of older people's lives. I guess the millennial have had enough and said screw the older generation.
I also guess corporations are seeing the attitudes from younger people and where their social and political leanings are. Corporations maybe embracing and supporting these BLM protest because they see protest as future indicators of their consumer base. As publicly traded companies, they need to anticipate who their future consumers are, and the future consumers, at least from the makeup of the protests, will be more diverse, more female, and more liberal.
