I'm not going to comment on the linked article, other than say I think it contains serious mistakes in describing what OCSP is for and errors in other statements. In the background there is a war going on, but it isn't what you think. It is a war between malware creators and OS creators. From my perspective it goes like this: To "identify" malware you need signatures. Signatures need valid certificates. Signing keys…
If you are not going to allow "malware" on your computer, you're giving the power to Apple to label anything they don't want you to run as "malware".
They already have a walled garden on the phones and tablets, which has greatly benefited them. They can deny anyone access to publish software and they have exhibited everything that is obviously anti-competitive.
Now, they're bringing it to laptops.
Honestly, I don't see anything happening to Apple anytime soon. They're way too well off and they have very important government officials in their pockets. The best thing that may happen will probably come from the outside... like the EU antitrust investigation that is going on. Even so, it's not going to stop, not anytime soon anyway.
