All big guys have similar attitudes
I worked for a 5 person UK based company in the 1980's when the boss showed our prize product to National Instruments with a view to them purchasing it.
Everything when quiet and then Lab View came out (at that point a not very good copy!)
The boss rang up his contact immediately we became aware of this and were told that NI would tie us up in legal costs until we went under, and so what were we going to do about it?
