Are you claiming that Hamas does not seek the destruction of Israel

I am claiming that Hamas has no hope of destroying Israel no matter how many interested Saudis want to donate to them to so they can feel better about being rich.
You however appear to be pretending that the team down 1000-nil is a real threat. Why exactly?

Tridge owed Linus nothing

Does it matter? What matters is that Tridge fucked around and violated the licence and the fallout hit Linus in the form of having to do a lot of unnecessary work. Being only human this appeared to have made him angry.

I have no idea why you brought the GPL into it

Try reading the above post entire instead of key words then. It's only three lines long. I can wait.
If you use software it's only fair to stick to the licence the creator wished you to use - if you don't like it use something else.

You cannot yank your software if it's free, regardless of what license it's under

If someone violates the terms of your licence of course you can.

Linus blowing up at Andrew Tridgdell for "reverse engineering" the bitkeeper protocol comes to mind.

Since it meant that Linus had to go and spend time writing git after bitkeeper was taken away from him due to that licence violation he had a very good reason to be angry.
Do you think the GPL is the only licence that should be respected?

Welder now gets that the situation is being seen as serious and can not just be fobbed off.

Sometimes you just get ignored if you do not use appropriate language to convey how serious a situation is.

From the standpoint of fighting a war for survival, which the state of Israel is doing

That is how the propaganda frames it. However it's not 1948 any more and there are no serious threats in the region to such a powerful nation. That may change if ISIS unites everyone from Lebanon to Iran and has a decade or two to get their shit together but I can't see that happening outside of their dreams.

Since it's the wrong continent and someone will eventually correct the wikipedia article you are correct, it will go away almost instantly.
The real problem in Africa is a different story but like foot binding before it (in another part of the world obviously) it's been slowly going away as well.

The problem is that any suggestion that the current government of Israel is imperfect is taken as "anti-semitic".

I like Israel, it has a lot of good things going for it. However currently it is run by a bunch of fucking fascists who have timed yet another pogrom into Gaza to coincide with an election. That seems to run contrary to everything Israel is supposed to stand for.

It's still not easy and is still very expensive for the reasons given above. There may be less oxide in the shavings than in rutile or titanium dioxide but you still have to get rid of it before it can be melted down - and with a high melting point plus a need to keep oxygen off it's not that cheap to melt the stuff either. Reducing waste with titanium (or titanium alloys) has more of a cost benefit than just about any other non-radioactive metal since the reprocessing cost is high.

refining Titanium from raw 'ores'.

It's gravity separated out of sand so the mining part is as cheap as mining gets - reducing it from an oxide is the very hard bit.

In my country the greens are pushing for broadband and the "conservatives" are opposing it because major donor Rupert doesn't want the competition.

Sadly while it would be "bullshit" with stainless steel it's not so simple with titanium. Recovering metal from the shavings is not as simple as just throwing them in a pot and warming it up, even if you do it in an inert atmosphere.
The entire reason why titanium is expensive despite being made from very plentiful sand is because it's bloody hard to reduce the oxide and those shavings are covered with it.
That very hard to move oxide is why it's so useful in medical applications but it makes it a difficult material to do anything with.

Also using powder directly removes the step of forming the stuff into large blocks. It's vastly easier to make titanium metal in powder form than fully solid ingots with consistent properties.

The machined Ti is reclaimed

It's not easy to reclaim (titanium oxidises very easily so the scrap has to be reduced again, almost as hard as getting it out of sand in the first place) and the consumable costs to machine it are not trivial. Your cutting tools are ripping into titanium oxide, and guess what a lot of the cutting edges of those tools are made of? You can't guess? The answer is stuff like titanium nitride which is not a lot harder, so the tools wear down very rapidly. Using diamond doesn't help much either. It's a very slow and expensive way to do things but used to be better than any other way available.
This development is interesting because now it is available it's a lot easier than your "just mill it out of a block" suggestion which is why it's being discussed at all.

given the inherent porosity of sintered material that give purchase for pathogens

The milled stuff has been treated for years to produce a porous surface to allow bone to grow into it. I heard a paper presented on that in 1999 by some Japanese and Californian researchers and it's apparently become standard practice since.

When they say 3D printed do they mean a metal mill

It almost always means an additive instead of a subtractive process. Milling cuts things away and is subtractive. 3D printing sticks things together so is additive.

or can we 3D print with any random material now

Yes so long as you keep in mind that 3D printing describes a wide range of methods instead of a single one. In this case it's sintering metal powder one layer at a time with a laser. While expensive it's got some things going for it:
It's easier to produce titanium as powder instead of large solid blocks.
It's expensive to machine titanium from those solid blocks.
Titanium is expensive in general so methods like this with very little waste have an immediate benefit.
Laser are very cheap these days, give very good tolerances and don't really use all that much power. After these parts are made they probably don't need any more finishing than a bit of sandblasting.

And if so, why not use the far more tried tested, and better alternative milling?

Because we already know methods like this have several advantages over milling, electrochemical machining, casting, hot isostatic pressing, macro scale welding etc. It's not for everything but this application seems to tick all the boxes where laser sintering makes more sense than anything else.
