"Paid" is the key word. Follow the money.
That is why I declined the offer from ZWO last year for a free ASIAIR "Plus," and other "gifts" of new hardware from time to time from ZWO. One year, they wanted to send me moon cakes for Chinese New Year.
I also don't want to deal with working through ZWO's bugs. It is one thing helping others when it is cloudy for me, and another thing when I am stuck with untested, flakey equipment when the sky outside is clear.
On top of that, I don't want to deal with "gifts" from a foreign country when it comes time to file my taxes. These shills on YouTube and FaceBook must have good accountants. I already avoid stocks from foreign countries since you need an entire tax form just to deal with their dividends; and those are even legit transactions, and not bribes.
