GoPro founder and CEO Nick Woodman can't be ousted, since he's the top shareholder and still owns about a third of the company's shares.
But under Woodman's leadership, GoPro leapt into new markets -- like media content, VR, and drones -- without doing enough due diligence. Those efforts all flopped, leaving GoPro stranded in the saturated action camera market it was trying to escape. The launch of the Karma, which was hit by an embarrassing recall, is symptomatic of GoPro's execution issues under Woodman.
I see some similarity here on Seagate.
