It's not really the core banking business in the US - interest is only about 50% of income for large banks.

And check out page 38 of BoA's annual report: http://media.corporate-ir.net/media_files/IROL/71/71595/BOAM...

Interest income was $44.7 billion, non interest income (aka fees, trading, and services) was 42.6 billion.

Lending is still the biggest segment by far and some of the fees and charges are closely related to the lending business.

Also, most of the other segments are not exactly what I imagine tech companies will want to do either. In the case of BoA that includes the entire business of the former Merrill Lynch.
