Hey,
The logo is the sole possession of the person the work is created for. Either Richard or Jake are the sole owners of the logo, not HostSuite. Thats like me making something with "Google" on it and then Google coming to me and saying they now own my work because I used the word "Google" on it.
Jake is a pretty cool guy, so please don't try to drag his name down because of your poor reputation around these parts.
If the works were created for HostSuite for Jake, then it is upto Jake how they are used. It does not matter that the images bear "HostSuite" on them, it is the matter that it was made for Jake.

EDIT - No Darren, it does not work like that. You do not rightfully own the logo, Jake was hardly the messenger. He asked Richard for a favour which was completed on his behalf. If it was not for Jake there would be no logo at all.
In your example, if User B is a Co-Owner then he has an equal share of the equity and he owns half of everything. If he leaves the project, he is well within his rights to take what has been made for him/he has created.
