I'm not even sure selective quotation is really a problem. Selective replying happens regardless of whether they are quoting or not, but is just more explicit when they are documenting which parts they reply to.

I agree. I still do this. But nowadays lot of people feedback that they do not understand my way of replying. Compared to many of my early digital acquaintances I was socialized quite late on the internet starting in 97. Compared to my colleagues I often feel old and out of sync with my style of long form written communication.

Some clients, like Outlook, will actually collapse the original email and only show the top-posted reply. An inline reply would appears as an empty email in their client.

I have this same problem and would describe it similarly.
