No, it is not a subjective term and you would do well to reacquaint yourself with the meaning of subjective VS objective.Grind is purely subjective term. What ED objectively have is lineup of activities, which have certain gameplay loops attached to them. You can mix them up, vary between them, but they are certain, and they repeat themselves - as any games have it.
Now what is SUBJECTIVE is your attitude towards it. I discussed this with my friend yesterday and we got into very heated argument. His argument is that there are group of players who can't help it, they threat games as competition, with anything really, and for them having goals in such games as ED is bound to make them see gameplay loops as grind - because they see them as BARRIER between them and goal. They don't see combat, trading, mining, doing missions, etc. as gameplay or content really. It is that something they have to do over and over again to reach their goal. This is how mostly players complaining about grind in games in general sees this.
My point was that it is their choice to engage in it after all. Way friend described it as it was almost evil for developers to make games like ED in nutshell. We dropped subject because we just don't like to argue like that, but overall I got impression that this is something more of emotional state and some reactions regarding Engineers, PP or anything that repeats itself really are better understood by me. I just don't see ED that way and I guess that's fine. It is not me who have to deal with this, it is them.
Subjective: Based on ones opinion or how they feel about something
Objective: Based purely on fact, like existing or not existing, and not on how one thinks or feels about it.
Your view is subjective that you say there is no base grind and that they have a lineup of activities.
It is an objective FACT that the whole game is based on tediously long and arbitrarily boring grinds and that they do not, in fact, have a lineup of activities in the mission system. You have a mission board that spawns maybe 5 missions and they are always the same 3 or 4 with no deviation; and that's IF it spawns any at all.
This game is objectively a masterpiece when it comes to the galactic scale and objectively trash when it comes to basic functionality. The game is 2 years old now and instancing still does not function. That aside, the game can still be subjectively good to you if you enjoy exploration or any other activity and aren't bothered by all the short comings.
Me saying the game is bad because so many things are broken is objective.
Me saying the game is bad because I don't like HOW the mission system is set up is subjective.
Content is lacking in this game, subjectively, as I and many others feel that implementing RNG for literally everything is a lazy cop-out. If you enjoy doing the same mission over and over and over and over again, or trade route or whatever, then subjectively it does not lack content.
I hope we are now clear on subjectivity and objectivity. Have a good day.
