While the statement is true, it doesn't apply here in my opinion.
What we have in paragons is a deliberate decision to cater more to the roleplayers than the minmaxers. This isn't "wrong" in itself, but its obviously a very polarizing decision.
I haven't delved that deeply into the DLC yet, but I've been curious and cautiously optimistic about my first new playthrough. It feels that everything is slower, and minor decisions (that minmaxers would call needless micromanagement) actually make a difference. I need to choose between using my leader pool to either explore space, or to develop my planets for example. Now it feels that since I cant have everything at the same time, the choices matter more. It also seems to slow down the game as a whole, which is also not necessarily a bad thing.. But of course, this is just my own personal opinion.
Minmaxing and micromanaging is the antithesis of grand strategy. Grand strategy (and the concept of strategic thinking itself) doesn't mean "really trivial decisions, but like.. thousands and thousands of them", it's looking at the strategic picture and making the big picture decisions.
"Where should I station the bulk of my fleet" and "should I attack that hive mind so I can expand my empire or try to ally with them as a buffer against the exterminators next door" are strategic decisions.
"Which scientist should conduct the research on the jump drive project?" is a decision for a middle manager at lockmart and the person in charge of removing a planetary obstruction is a project manager, not the god damned governor (who is presumably governing the planet and not spending every day at the site making sure they're loading the trucks correctly.)
So it's not that paradox is catering to roleplayers, it that apparently Stellaris is actually a grand strategy game where you make strategic decisions (on a grand scale even).
They need to kill off this micro and anything like it, not to punish minmaxing but because if something can be micromanaged like that it's a huge red flag that it's not a strategic decision.
Ed: if I had unlimited time and money, I'd pay someone to do a study across stellaris and other strategy games to figure out what percentage of time players spent gathering information and using it to make high impact strategic decisions and what percentage is doing low impact configuration changes to get a 50 credit voucher that can be applied to removing a basic terrain blocker.
