I agree with Capri Racer, after having Michelins on all my vehicles for the last 8-10 years it's normal.
It's really amazing how other "name brand" tires can go through their life and not crack, or have the sidewalls "flake off"-but expensive Michelin tires dry rot/crack/flake and it's normal.....
Your concerns are valid and I admit to being alarmed the first time I noticed this on my wife's Wrangler, with only around 30k on the tires. Then I did a bunch of research, and kept a close eye on them.
But since they made it 160k miles (That's not a typo - 160,000 miles) and the cracks remained pretty much the same throughout their life, I'm a believer.
Now to be fair, if chunks had started coming off things would have happened differently; but never lost one piece of rubber from the sidewalls. I liken it to one variety of steel that is designed to rust on the outside to form a protective layer to preserve the metal underneath. Perhaps Michelin's rubber compound "gives" on the outer layer to protect the integrity of the layers below. I don't know; but what I do know is they never leaked air and lasted 160k.
Hey, if it's a concern, don't buy Michelin. We all like what we like.
