Well, that can be true on some things. But I remember the iFans proclaiming how NFC was a useless gimmick 2 years before Apple included it for Apple Pay. Or how LTE wasn't needed because HSPA+ was good enough. Or how 2gb of RAM was not needed. Or how large screens were a complete waste because you couldn't use them with one hand. Or how they made fun of the Samsung Note Stylus, but now with the Apple Pencil, a stylus is cool. Personally, I think Applke holds tech back on purpose simply to keep fleecing customers of their money.
I disagree. I see a lot of people just lump everyone that likes apple into a collective, but that's not the case. When the iPhone 5 came out, a lot of people were upset they didn't go larger, and many left for android handsets and then came back when the 6/6plus came out. You also saw a lot complain about the 6/6plus being too big and hold on to their 5S, which is why apple is releasing the SE. When the 4S came out without LTE, at the time LTE was a huge battery drain so many proffered the better battery life of HSPA. When the 6 and iPad air came out with only 1gb of ram a lot of people were complaining and kept complaining until apple addressed it. And NFC really hasn't taken off anywhere other than mobile payments, I generally keep it turned off on my phones because I hate seeing that ugly NFC logo cluttering up my notifications panel.
Not saying apple is perfect by any means, but:
1. Things advance, so something may not be needed or wanted today could be crucial tomorrow (4k screens anyone)
2. People do change their minds (there was a time I thought the 4.1" screen of my Moto Atrix was perfect, and now I prefer the 5.5" of my edge).
3. All apple fans don't automatically think the same, so when one complains about big screens one day and then another apple fan rejoices when they have bigger screens the next, it isn't because apple fans didn't like it until apple did it, it was 2 different people with different wants and opinions.
There are apple fans like the ones you describe, just as there are blind android fans, but they're far fewer than people assume there are.
Where I do agree is apple holding back software features on older handsets. It's something most hardware manufacturers do and I wish it would stop.
