IBM didn't open the PC architecture. They decided it wasn't worth much, used external suppliers for everything. Others simply copied it. Ooops.
As a matter of fact, they sued the early cloners (like Compaq), but they lost the suit, because Compaq managed to clean-room reverse-engineer the BIOS chip (which was one of the few proprietary components.)
Well, they did in the sense that they made the interfaces open and later licensed their proprietary technologies. They tried to regain some control when they introduced Microchannel, but it was too late by then.
IBM never licensed the proprietary parts of the original PC. They were cloned in a way that IBM couldn't prevent.
Yes, they tried to change that with MicroChannel, but as you said, it was far too late. There were so many PC-clones by then that the market responded by saying "then we won't buy IBM anymore".

IBM could have killed the clone market the same way Apple did if they chose to...
Not really. Apple was able to kill the market by refusing to release updated firmware to the clone makers, by making firmware that is very difficult to reverse-engineer, and by actively prosecuting those who redistribute the firmware.
IBM never had this option. BIOS quickly left IBM's control when Compaq was able to legally reverse engineer it, and when companies like Phoenix and AMI started selling their own BIOSs to everybody in the world.
Ditto for the operating system. Apple was, and still is, the sole source of Mac OS. If someone makes a clone, Apple can tweak Mac OS to not run on it.
IBM never had that control over any PC operating system. IBM gave Microsoft full license to sell MS-DOS for any non-IBM computer. OS/2 had a similar license. Other operating systems (CP/M, Xenix, etc.) were completely third-party products.
With no control over the firmware or the OS, there is no way IBM could regain control over the PC market. In hindsight, they lost that control before the first PC ever shipped - when they allowed Microsoft to retain control over DOS. Of course, they had no way of knowing that at the time.
I will gladly pay real money for DRM-free content.
And I'm sure you already do. They're called CDs.

Your dollar is your vote, and I'm very surprised people in this forum would vote for DRM by buying even one single thing from iTunes. I'm dying to give Apple my money to buy DRM-free stuff, but they don't seem to want it.
I buy products because they offer what I want for a reasonable price, not to make a political statement.
I buy the occasional iTunes track because the DRM terms are acceptable to me. I don't buy DRM content from other vendors because their terms are unacceptable (and because they don't play on my Mac or on my iPod.)
When new kinds of content comes out with new DRM terms, I'll make my purchasing decisions based on how much those terms affect me, and if I find the conditions acceptable.
I don't have the time to be bothered with fighting a war against the whole concept of DRM.
(BTW, have you ever bought a DVD? There's plenty of DRM in there too, you know.)
