I would be very careful with generalisation ...

Would the base problem not be that the classic model of "1-year support for a
fixed fee" creates a false illusion ? How can you expect a support company to
get into intensive research of a complex problem if this just creates additional
cost, but no additional revenue ? For a big customer, that is paying hefty
yearly fees, it is obvious to do this investment, but for a small customer ...

Seems very logical. Those who pay extra for extra work, will get extra
work delivered. Those who rely on the 1-year support for a fixed fee
will get what remains. IMHO this is best resolved with just charging
hourly: you pay for what you actually got ...

I have seen a number of "small" support companies deliver excellent
support to e.g. large semiconductor companies.
