Microsoft ads
This isn't a coincidence anymore.
Every time I look at the mass media, at an article regarding GNU/Linux, the whole page literally swarms of Microsoft ads. Microsoft's marketing really seems to focus on pulling users away from GNU/Linux these days.
This is very apparent if you go to a site which has content on a wide variety of subjects, such as heise.de or The Register. Pick a subject regarding GNU/Linux or other Free Software – Microsoft ad. Pick a subject regarding Microsoft, or even something completely unrelated to either of the two – no Microsoft ads.
They usually also pick those horrible lead-in ads, which reduce the are available for the article text itself, so that it becomes much less comfortable to read. I suspect that is on purpose.
