Just to add to prof. M.F. Weiner's optimistic note:
Having more than 4000 hours of therapy, psychoanalysis and supervision online (starting daily online work in 2003), I can assure that an experienced analyst / therapist can perform good therapy not only in its Ego-supportive or cognitive modes but in evocative as well as long as s/he takes into consideration two important limitations – functional blindness and limited perception. There are other "know hows" too but the two above mentioned are most important. Functional blindness means that all seems to function normally, yet you don't know what it would be if the same material would unfold in face to face setting – "normal functioning" may betray you and your patient. Limited perception means that you inevitably miss important details – odors, body movements, dress and makeup details, environment etc. This being said, my experience convinces me that one can do a really good psychoanalytic therapy, deeply enough exploring unconsciousness and at least some transference- countertransference constellations. Whether we call it psychoanalysis or psychotherapy doesn't matter much to our patients nor to ourselves.
