The HDCP (copy protection) part of HDMI is still controlled by Intel same as
DVI.

Clearly there was a time when Apple chose technologies that were
either ahead of their time or proprietary. A list of Apple firsts:
3.5" floppy drive - became an industry standard
Standard networking via Appletalk - years ahead of PC networking -
Apple eventually move to Ethernet when it emerged as the industry
standard. The first Mac products with industry standard RJ-45
Ethernet connectors introduced in 1997. Apple introduced products
with Ethernet in 1990
and chose to use a proprietary AUI connector. The reason for this was
that both twisted pair and coax Ethernet implementations were widely
used, thus the AUI connector provided a simply way to use either; the
reason the connector was proprietary is that the industry standard
AUI connector was the same as the connector Apple was using for
monitors, and they were worried about having two different ports on
the machines using the same connectors.
CD-ROM - became an industry standard
Firewire - a significant factor in Apple's dominance as an
Audio/Video content creation platform.
Display Port - an industry standard that is now beginning to see
widespread use.
I could go on with things like a mouse, touchpad, mag-safe power connectors...
The important point is that Apple is now using industry standard
connectors for most products, but is often the first to pioneer a new
standard.

Too bad you are wrong about this.
Amazon is showing monitors with display port from:
Asus
Apple
Dell
HP
Samsung
Thinkvision
Viewsonic
Every major manufacturer of graphics cards (pci bus) is selling
products with displayport.
And HDMI is limited in resolution, thus not a candidate for higher
end workstations and monitors.
And there are a ton of third party display port adapters for VGA and
HDMI as well as multiport hubs.

Not all dongles/adapters are bad when the port supports multiple standards.
But the real beauty of Display Port (and Thundrebolt) is the physical
size of the connector. Expect to see this in many products in the
future.
Also expect some innovation as third parties develop Thunderbolt hubs
and peripherals for many applications.

The point was that TVs also have migrated through a variety of
interconnect standards, and in the end the industry created a
proprietary interface (HDMI) with proprietary copy protection,
because they did not want to let Intel control the copy protection
standard via DVI.
Both HDMI and Displayport/Thundrebolt will see widespread use...
