“BLACK LIVES MATTER” GOOD, “ALL LIVES MATTER” BAD: Mark Zuckerberg tells Facebook staff to stop defacing Black Lives Matter slogans. In the Guardian, so not a hint of awareness:

The company is investigating why staff are still ‘maliciously’ writing ‘all lives matter’ on campus walls, despite pleas from Zuckerberg himself. …

Zuckerberg expressed dismay that, despite his “clear communication” at a company question-and-answer session the week before that such behavior was “unacceptable”, employees had continued to change the messages.
