Unless like in your case when the become your best friend and you start giving them advanced technology for free.
I do like that so many talented foreigners have decided to let us use their excellent software for free
I guess so if you consider cheap foreign knock offs to be excellent software. That's like going to Tijajuanna and claiming the fake Nike's you can buy for a buck are excellent, how much more ridiculous could you get. I don't know but I'm sure you'll show us shortly LOL.
Almost all software is a knock-off in one way or another. The original Bell Labs UNIX was a knock off of MULTICS. MSDOS was a blatant knock-off of CP/M in the way Linux copies UNIX -- by mimicking the function, but with entirely new code underneath. Windows NT was a VMS knock-off in many ways, even had the same architect.
And if by "cheap" you mean quality, sorry bud but open source has achieved some of the highest-quality software on the general market. Closed IE can't compete with Firefox. Closed Windows is getting trounced in supercomputing by open source. Open source still runs most of the Internet.
So, when are you going to stop using the "cheap foreign knock offs" and go with proprietary US software only?

That is a trademark issue. You always get that confused.
