While consumer drone leader DJI makes headlines at this week’s CES with new products, GoPro announced Monday it would pull out of the drone business after it sells its remaining stock of Karma drones.

The news comes after word leaked last week that GoPro was about to lay off more than 250 workers from its aerial division. The layoffs and Karma kill-off comes amid estimates that GoPro’s fourth-quarter revenues will fall more than $100 million short of projections.

Things go from bad to worse for Angry Birds developer Rovio. Having seen its CEO step down in August, now the Finnish studio has announced that job cuts are on the cards — to the tune of up to 130 people.

In a blog post, outgoing head honcho Mikael Hed claimed that these cuts were part of an effort to simplify the company after a period of ambitious growth that is considered no longer sustainable.

Microsoft is going through some major turbulence. Today it has announced major layoffs, beginning with 13,000 positions to go immediately, with a total of 18,000 expecting to find themselves out of a job sometime during 2014.

The vast majority of these sackings involve the company’s Nokia division. Microsoft acquired Nokia’s Devices and Services unit back in September 2013 for $7.2 billion. Along with taking ownership of the Finnish firm’s entire smartphone lineup — giving it complete control over both hardware and software– the acquisition saw 25,000 Nokia employees join the Microsoft ranks.

The current Microsoft layoffs means that up to half of the Nokia people will probably leave the company, although it will also likely signal the end for some previous Microsoft employees to allow for incoming Nokia talent.
