Looking for not best but accurate answer, can I fork odoo 9.0 CE ?

Does we rebrand with our own new upgrade or changes ? Shall I remove their logo from front and change mine ?

In case fork, can companies able to apply their private license ? I think now new license more better for who are not partners.

Please advice accurate answer.

Your question astonishes me after your numerous unsubstantial negative remarks about Odoo.

I hope you astonishes when fabien remove his own tweet and change odoo license too. I had negative remarks on odoo always where it had hell issues or performance, in case we rebrand, we upgrade for better level.

I wish you good luck with your plans and I'm waiting to see your "better level" odoo. But you should speed up your process, because you did ask the same thing 6 months ago and got a proper answer, and after six month you are asking the same question again and get the same answer. With this speed, your "better level" Odoo 9.0 will be ready, when we have Odoo 20.0.

Yes, you can fork it and you can do with it what you want. It is even allowed to apply proprietary licenses. See https://en.wikipedia.org/wiki/GNU_Lesser_General_Public_License  

But you have to make the code available to your customers if it is a derivative work, so that they are able to modificate it on their own and reverse engineer it, as stated in the link:

The main difference between the GPL and the LGPL is that the latter allows the work to be linked with (in the case of a library, 'used by') a non-(L)GPLed program, regardless of whether it is free software or proprietary software.

[1]

The non-(L)GPLed program can then be distributed under any terms if it is not a derivative work. If it is a derivative work, then the program's terms must allow for "modification for the customer's own use and reverse engineering for debugging such modifications."

As of the nature and structure of Odoo, whatever you want to do with it, it will almost certainly be a derivative work.

Means no useful fork of odoo possible, yes, in case we build own web UI from scratch we able to re-brand for front-end and keep backend as per 9CE license, with private modules.

In case, We only use base module of odoo and rest all module we create and with our own front-end from scratch, then somewhat yes, we can re-brand !!!

Ermin Trevisan

In contradiction, the new LGPL is even necessary to create "private" forks, this would not be possible with AGPL as Odoo 8.0 for example.

Finally let me know, in case we use odoo as only backend, frontend we create from scratch with other platform like #ruby, other web language language. No front end with any existing code, I am sure in this condition no one such had issue and license matters. !?

You should consult a lawyer specialized in this matter.
