Re: What exactly is objectionable?
To NDA - "this" whatever "this" may be could be considered normal
To pass ownership - might be okay - if paid up front - that is, you know what you are getting in advance. But not, imho, if they are evaluating it and decide to give you nothing. Maybe you found a patentable effect - and they just take it for nothing.
Finally, between the lines of what people are saying about the formal NDA - sounds like they are making an attempt to also own "future" aka "undisclosed" (to them) information you have. Who can say what you have at time X. Their lawyers contend you had it, but did not disclose fully - and so violated the NDA ownership transfer.
Also not heard - what court are (so-called) breaches of the NDA tried in. USA, Europe, India, ..., China? Also make a big difference.
