Hogwash. It's like riding a bike or ice skating, neither of which are all that enticing the first couple times you try it. However, once you figure it out, it isn't that bad, and once you've had practice and get really good at it, you'll find you are having way more fun than when you were falling down on your behind every five seconds.
I don't think that's a great analogy. You are presuming that people don't like the FSS because they find it too difficult or challenging, but I don't think it's that. Sure, with riding a bike or ice skating you can have a miserable time until you reach a certain level of proficiency, but the FSS really isn't that challenging or difficult to use.
I did play it in the beta, took me about 15 minutes (if that) to set up the bindings, and didn't find it particularly difficult to use (in VR), even with the missing blue blobs. But I didn't like it...
While I accept it's more hands on and active than what we had before, just being active or hands on isn't enough to compensate for the fact that I don't find the environment engaging or fun. It's just repetitively 'twiddling knobs', to use FD's analogy with tuning a radio not to demean the activity, and while I could probably put up with using it occasionally if the result were compelling, I definitely don't want to be doing that more than flying my spaceships. It's not why I bought ED.
In the game now, if I do missions, I'll drop into the nav beacon rather than fire up the FSS. The only reason I could imagine using it would be to find a HGE USS, not something I do very often as that in itself is far from compelling game-play. As to exploring, I won't be doing that again, because that means likely as much time, if not more, in the FSS than flying my ships. Sure, old exploring was passive and potentially time consuming, but boy have FD swung the pendulum a long way in a very different direction...
Anyway, as it's almost entirely avoidable when playing in the bubble I can adapt and live with it. But I'm stopping by here just to point out that IMHO, as the discussion about marmite and vegetables alludes to, this system, this game within the game, is probably something that players will either like or dislike, it's not a matter of getting used to it, it's just that the game-play involved is very different to anything else in ED, or indeed the previous Elite games, none of which have taken us out of our cockpits in the way that the FSS does.
So, for those who like it, great and perhaps they'll explore as much as FD hope they will. For those who primarily played for exploration and don't like it, well it's ruined their game to a degree, and I find the lack of empathy from some towards those players disheartening.
