To me, the progression of DLC for this game seemed clear:
DLC 1: US + UK, logistics + naval warfare overhauls
DLC 2: Germany + Japan, tech + air warfare overhauls
DLC 3: France + Italy, political + economic overhauls
DLC 4: Soviet Union + China, espionage + land warfare overhauls
But we all know they want to milk this for as much DLC as possible, they would never be so condensed.
I think it is pretty obvious, that Paradox tried in the past, is trying now, and will continue to try tomorrow to maximize profit on the game. Since they do not live in a controlled economy it is what I would expect, so it does not surprise, nor anger me.
Allow me to jest a little, but all of it being the truth at the same time.
The alternative to not chasing profit means the company cannot pay the employees and we know how those selfish employees are; if they do not get paid they will actually walk off the job. Can you believe that? You ever met an employee who did not care about the money? Heck, where I come from employees want, not just money, but paid time off for doing nothing at all! Then they want other benefits on top of that! It just never ends with those employees, always with their hand out. What's a business gonna do?
Jesting over.
I guess Paradox could have tried a different business model. Others do exist. If they chose to add more content and put it out faster, that would increase cost in a compressed time frame leading to a higher price customers would pay for the game. Of course higher price has the nasty effect of reducing the number of customers so the price has to be even higher. This leaves us with a game that costs more or without a game at all, as the game does not sell enough copies fast enough and the company cannot pay back the money it borrowed from investors to pay those pesky employees they need to fix the bugs the employees made in the first place.
Another model is to release HOI4 version 1.0 and then close that project down and use those resources for a different game, maybe a business simulator game.
The answer to fixing things in HOI4 and/or accelerating content creation can only be found in business and profit, so I cannot agree that milking DLC is a bad thing. On the other hand, I do believe that the executives of Paradox made a mistake in not putting more of HOI4's profits back into the HOI4 project team. While I applaud the company in producing profits, I would like five minutes of alone time with the executive responsible for not giving the HOI4 team a full time AI programmer, full time bug fixer, community liaison officer, full time history scholar, more portrait creators, hot tubs, basketball court, gun range to test WW2 weapons, and an arena for Sabaton's use when they drop by for a show at the office. Me and him got words that need to be said.
