1. Google's woes in Europe: The European Commission is expected to announce a major antitrust fine against Google over allegations that it pushed its apps on smartphone users and thwarted competitors.

2. Elon Musk apologizes: Tesla boss Elon Musk has apologized for calling one of the men involved in the Thai cave rescue mission a "pedo," or pedophile.
Musk faced an intense backlash over the unfounded claim against Vernon Unsworth, an expert caver who participated in the rescue mission that saved 12 boys and their soccer coach from a flooded cave in Thailand.
The executive said on Twitter that while Unsworth provoked him, "his actions against me do not justify my actions against him, and for that I apologize to Mr. Unsworth and to the companies I represent as leader. The fault is mine and mine alone."
Gene Munster, a top tech analyst and the managing partner at Loup Ventures, wrote an open letter to Musk this week urging him to rein in his outbursts and erratic behavior so he might "regain investor confidence."

"The violations are related to personal behavior that is not consistent with our ethics and core values, but not related to company strategy, operations or financial reporting," the company said in a statement Tuesday.
