"Last week, it emerged the owners were planning to radically shake up the Imagination's board of directors, prompting the resignation of Steve Evans, chief product officer, and John Rayfield, chief technology officer."
You missed out a couple of key details there though, right? The takeover was only allowed as the company was regulated under US law, and under the condition that China cannot move the technology. The company then moved to the Caymans and then the Chinese government (well, some Chinese government company) tried to overthrow the board and move the company to China. You know, agree to some document with the British government and then rip it up and throw it away.
Kind of like with Hong Kong.
