Over the past couple of years, I have seen an alarming increase in people concerned over China's efforts to gain a stronger foothold in the digital marketplace.
Interesting to see that now automatic system updates pop up once a day in Debian, at least in the ‘testing’ and ‘unstable’ flavours, better known as ‘Etch’ and ‘Sid’.
First I saw that on Ubuntu, and I thought: now that is end-user friendly. And unlike its proprietary counterparts, these updates don’t only care for your operating system, but for all of your applications as well, which shows how amazing free software really is.
