I don't know any personally, and can't imagine any that I know acting like this. On the other hand, I can see one getting discouraged, and retreating into a shell, and avoiding relationships entirely. Also, I think that if that happened, their fear of others would cause them to project such an attitude. Also, I suspect (based on private things), that some types will view the iSFP's behavior in this way, whether it is true or not. I'm thinking particularly of strong Fe types, because they see us taking but never receiving in ethical/feeling-type interactions. To be honest, from our perspective, we also feel that they are doing all the taking and we are doing all the giving, which could, IMO, give rise to a situation where an ISFP may feel frustrated enough, especially in relationships where he or she may feel no exit, that the ISFP may, in time, begin to actually act the way the other is treating them, and be bitter, exploitative, etc. I would most expect to see such a thing these days in parent-child relationships, or other family relationships where there is no real possibility of breaking contact.
To return to my point above, as to why Fe feels Fi is taking, and visa versa. Think communication styles. Fe is very much "outward" and Fi is very much "inward" in their judging. This causes differences in communication styles. For instance, Fi feels rather uncomfortable asking questions of a feeling nature, such as "how do you feel about this?" So, in interactions, will avoid such questions. Rather than ask, the Fi type, when giving of himself to encourage, or whatnot, will share something of him or herself--offer themselves up on a platter, so to speak, possibly in terms like this, "I felt like <this> when <that> happened to me." The actual point of talking like this is _not_ to just talk about oneself, but to act as a catalyst to the other party to get them to open up themselves--because _asking_ feels so very intrusive, plus, what question would not hurt--you see, direct questions are uncomfortable-feeling--we don't want to inadvertently cause more unpleasant feelings, so we go about it in a round-about manner.
Fe, on the other hand, being outwardly focused, is much more eager to ask the other "How do you feel about <this>?" And not merely ask, but to be specific. And also, they can be quite persistent. Since I'm an Fi type, I don't really know what they are thinking or what motivates them, so I can't speak for them. However, I can say that in interactions with them, I have found that they can be totally oblivious about my attempts to help them by sharing about myself. So you get this sort of situation, where i share, and they ask, I answer, and they ask, and they are feeling totally unfulfilled in the interaction because I am not asking _them_ questions. To them, it's all entirely one-way. On the other hand, I feel like it's entirely one-way, because they never, ever open up themselves, and share of themselves. All they do is ask me intrusive questions, without ever opening up about themselves. Now, this doesn't happen so often, because I've learned that one should also ask questions, but then another problem arises. Because it is not something I feel comfortable with, my questions tend to be generic and very awkward, so despite my attempts to open up and ask horribly awkward questions, they still feel like I'm being reluctant, and not "open" enough for them...
In any case, to summarize for the tl;dr part, Fe can feel like Fi is very self-centered in interactions simply because of the differences in our communication styles. I sort of learned this stuff years ago, long before I heard of Fi and Fe--namely that some people need you to ask them--despite how awkward it is for me to do so. But honestly, when things get tight, and the tension mounts, I find it much harder, and may end up just shutting down, especially if, despite my efforts to help, they keep pushing, without any intention of sharing any of the responsibility for the conversation.
So, I think that this may actually play a role in the description you mentioned. Not, mind you, that an ISFP _couldn't_ act this way, but some of this, I think, simply stems from a misunderstanding of how strong Fi types interact and _need_ to interact. Push them out of their shell too much, and you get that explosion of Te with IFP types. I don't know what you EFP types do--disappear in introversion? I don't know, but push Fi too strong, and the response cannot be pretty...
