You can be an "authorised Siglent distributor" without a contract with Siglent? Interesting.
If info is public knowledge, then confidentiality doesn't apply.
Yes, sure. But, to stick with the most recent example: Have the SDS800X HD specs been public knowledge before tautech published them? I still can't find them anywhere via Google. In my understanding, evaluation units are with a few beta testers -- surely under CDA -- and a preliminary datasheet has just been sent to some distributors, with instructions not to share the document.
On a related note, I am really intrigued that tautech claims not to have a contract with Siglent. How do they "authorize" their distributors? Is it some kind of ritual?
I think there is a misunderstanding in terminology.
You originally said "he is on contract" which has different meaning from "he has a contract".
I know, English is infuriating sometimes...
"he is on contract" means he is in Siglent's employ. Meaning, he looks down and listen to every word boss says.
"he has a contract" means exactly that. There is contractual agreement of sort on a business cooperation.
Having a sales contract (being Authorized sales partner) has quite a narrow scope. I'm talking here in general.
They will specify quotes, pricing structure, deliveries, some kind of confidentiality agreement.
They don't get to tell you how to do your business. Or behave.
There are many things that are not part of it. You get quite a lot of rope.
If for some reason they don't like how their brand is represented by you because of your general behaviour not mentioned in contract, they can call you up for a meeting and have a discussion. It is up to you if you care.
If they decide your representation is not to their liking, they can always revoke your status. Or threaten with that. It is up to you if you care.
Same as if you are not happy how company which products you are selling treats you or your customers, you complain to them and see if you can resolve the issue. If not, you can always start selling something else. It is up to them if they care.
That is how it works, simplified.
