I suppose this is the very definition of developer integrity.
However it’s also worth noting that they were spending that time on other projects making them likely even more money. HL3 isn’t going to have live service or esports applications that make money like their other games do. It probably won’t be a big earner compared to those other games.
Valve are also a privately held company and the rumour is the top people there are crazy rich, and even those further down the ladder earn a lot more than they would elsewhere. They don’t need HL3.
Portal 3 seems like the easy money grab. That had more lasting pop culture relevance, and "it's more Portal" would be enough for a bunch of people to buy it.
We all want HL3, but other than the story it would probably be fairly stagnant in terms of gameplay - nothing new has really happened in the genre.

They dont have to do anything new, just make it good enough, like Titanfall 2.
For what it's worth, I never even wanted Half-Life 3. I just wanted Episode 3, which was what they originally promised. It didn't need to be some gigantic groundbreaking thing, just another episode to finish off the story.
In short, they started working on episode 3, and made it about the point where the game development progresses from "here's demos of what could be set pieces in the episode" to putting together the sketch of the game narrative [1] when the developers were pulled to crunch for Left 4 Dead. After Left 4 Dead released, Gabe felt the window for an HL2e3 had closed, so it would be HL3 instead... and that because HL1 and HL2 had both heralded genre shifts, HL3 needed something to push that shift as well. But there weren't any such ideas for that shift (except maybe VR, which hasn't exactly panned out), and Gabe also felt that releasing a HL3 just to complete the story wouldn't cut it, so it never got made.
Which pretty much matches everybody's speculation for the past decade.
[1] About 18-24 months away from being releasable at that point, to give a sense of how far from complete it was.
> I believe they also said they don't want to do more of the same
I've heard this too, with Half Life they want each game to be groundbreaking. Arkane have done great games, but they're not all groundbreaking, and arguably none of them are to the level that HL1/2 were.
I guess they could, if not flat structure and billion-dollar yachts and what else is there.
But Gabe has said Half-Life specifically is what they consider their ground breaking series now. So there won't be a 3 until they can push a boundary again like the first 2 did.
Basically, they wanted more than just simply finishing the story, they wanted to make some cool new features, similarly to what HL2 was compared to HL1.
This is all speculation based on code leaks, and it's possible this is all true and they still don't release anything because the project stalls. Supposedly the game has moved into the later stages of development, but I'm not fully convinced by that part of the leaks.

Valve has been mostly silent on the issue (after hyping up EP 3 themselves).
