They basically re-report press releases. I've dealt with The Register as well as their sister publications back when I was still in product (especially during shudder RSA).

The Reg keeps a snarky tone, but immediately becomes deferential once a vendor begins a content campaign with them.

They also operated a bot account on HN for years that was spamming Register articles for almost 3 years and accumulated 66K karma until I and a couple others complained about it.
