I would put money down on the fact that the majority of 1D users don't stop their lenses down. So many users of this camera shoot primarily sports or some other type of action photography where their lenses stay wide open, or don't go narrower than f/5.6. So, to them, sensor dust and weird lines are indeed a nonissue.
The occasional time when these shooters do stop down and notice their sensors are dirty they clean it quickly and off they go again.
This is kind of true for me. If shooting sports with long lenses, it is 99.9% of the time wide open either because of dark venues or for subject/background separation. Similar is true shooting weddings. Studio portraits however are often at f/8 so I can get nose and eyes in focus. Here dust does become more of a problem, but usually only larger specks, easily resolved with a quick cleaning. I've also used these cameras for architecture and dust has been a major problem if I don't clean the sensors before the shoot. In this situation, I've had similar serious dust/specks problems with both the 1DX and 1DXII and it does seem like the top corners are the worst. My 1DX is currently at 997K actuations and the 1DXII is at 433K. Both were dusty for a recent shoot where I often stopped down past f/8 with wide lenses. After that I did a dry cleaning using the Dust-Aid 'stamper' tool ahead of the second edition of the shoot a week later, which helped a fair amount. I generally try to avoid wet cleanings whenever possible. I'll use the stamper for overall cleaning and follow up with the sensor-pen and SpeckGrabber tools to target individual specks.
My Leica digital M cameras have actually been more annoying than my 1DX models, but I typically use those with wide angle lenses and very often stopped down a fair amount. It's not uncommon for those to collect quite large bits of dust at inopportune times. They're essentially mirrorless cameras, though the shutter is always closed, but I do change lenses a lot. BTW, for the last few years there has been an ongoing recall by Leica to replace the M9 sensor due to the original cover glass specifications resulting in its coating degrading over time, particularly in more humid environments. Eventually 'pinholes' develop. Those appear as specks with a dark ring and a lighter center. My M9 eventually developed the problem and Leica replaced the sensor at no charge (though they recently stopped offering this as a free repair).
If I shot only Canon and did a lot more architecture and landscape work, I'd probably settle on the 5DS model. But the majority of my work is action related, whether it's sports, events or weddings and the 1DX models better suit my requirements. I have to admit, for most of what I shoot, sensor dirt/dust/oil specks have been pretty much a non-issue.
