A little perspective:
I bought my nanoVNA V2, and also a spectrum analyzer, on Ali Express, well
before I even knew about this user group. I came across it while looking
for something else, and it immediately caught my attention. I had used a
full feature VNA and spectrum analyzer once (costing about $100,000 and
$30,000, respectively, or so I was told), and said to myself: hey, this
looks neat and would come in handy for various projects I'm working on. I
chose the model and the store on Ali based on getting something that would
cover the 2.45 GHz ISM band, at a price less than $70 (to avoid paying
customs), and generally at minimum price.

Unfortunately, the hardware arrived with almost 0 documentation. The only
thing sent was a menu map, which was more or less useless. I was given a
link to website, which had some minimal instructions which could not be
carried out for calibrating. Corresponding with the vendor was completely
unsatisfactory -- I am sure they have no idea what they are selling. For
them if they sell a VNA, a pair of sneakers, or sex toys -- its exactly the
same thing -- what is the profit margin. (The 35-4400 MHz Spectrum Analyzer
came with even less documentation, and I have not yet managed to get it to
work).

I had never heard of OwO, Hugens, or any of the dedicated people who
developed firmware or software, or help other people on this group, until I
came across this group searching for some kind of manual. All power to all
of you! And many thanks!

But everyone should be aware that there is a commercial jungle out there.
My suspicion is that many more people buy a nanoVNA because they saw a
commercial advertisement, e.g. on Amazon or Ali, rather than from reading
this group's discourse. Thus appeals in this group to respect the
developers' wishes will probably have little effect. My advice to all
developers, of whatever, is to first decide what your motivation is. If it
is to profit from your work, which is perfectly legitimate, then you should
take all of the legal precautions necessary, e.g. patent protection,
secrecy, etc. This can be quite costly - probably a minimum of $10,000 for
each country over the lifetime of the patent, if you know enough to file
yourself (otherwise twice or thrice this figure). And if you need to defend
a patent against infringement, the costs can easily get to the M$ range.
Know that Murphy's law applies here - if something can be copied, and if it
is worthwhile to copy, then it will be copied.

Or, a developer can decide that his or her motivation is not monetary, but
rather helping mankind, helping the profession or the hobby, or even
obtaining or strengthening one's reputation in the technical community.
Then you might tell all and share all, and feel some satisfaction that
others are benefitting from your efforts. In my opinion, any middle ground
between these two approaches is apt to be frustrating.

I asked?, not forced, people to not help vendors that are selling copies
of my design against my will.

How hard is it to simply STOP producing and selling copies of my design?
My request is as simple as it gets. Is it that important to Hugen to make a
profit off of my work and screw the original developers over while doing it?
