I should have said ONE OF the most restrictive, in the case of
libraries it doesn't work well, because it restricts the user to only
producing free software. MySQL, puts commercial users between
a rock (The GPL which forces you to produce "free" software) and a
hard place (a Commercial licence where you hand your profits to
MySQL AB). To bring this back to IB/FB, the fact that FB has an
unrestricted, free licence, becomes a huge selling feature, even for
IB, because the user has the choice, not the library vendor.

However there is nothing to prevent the customer, from buying
those docs, training and consulting from someone else, once the
initial product is completed. So unless, you arrange a contractual
obligation at the beginning, the profit could evaporate very quickly.
