Consider that it actually hurts Canon's sales quite directly.
The most expensive thing (at least in the developed world) is a human being. Cameras are cheap comparatively. Now if I'm shooting an event (a wedding, a concert, whatever) singlehandedly, or even with a small crew, I am currently more or less limited to one camera per person...someone has to be tending the cameras, because 30 minutes after I press record they are going to shut themselves off to satisfy a few politicians sitting in Brussels. When I'm halfway around the globe.
But if Canon produced an uncrippled version of their cameras, I could buy more cameras, load them with high-capacity memory cards, put each of them on a tripod with a good vantage point, pull a good frame and focus, and set them off recording while I walk around getting different vantage points with another camera on a shoulder rig.
Canon sells more cameras. I have more footage to cut to without having to manage or hire more people. Everyone would be happy...other than the mentioned EU politicians (and some maker of video cameras in the EU...is Arri to blame for this?).
If you don't understand the value of this, I wonder if you've shot events. Or interviews. Or weddings. Or anything remotely documentary. Lifting the limit from 12 minutes to 30 minutes was huge in this generation of releases. Why is the whole world forced to crash up on a new, 30 minute ceiling then?
If it is a fear of overheating, fine, but it sounds like the worst ad for Europe possible.
