A faux objection is any objection that sounds like one but really isn’t. They typically follow the format of “I object because I want something else”.
The best way to recognize a faux objection is to ask yourself: “Did this person answer the question of whether the proposal will harm how we achieve the aim?”
If instead, they answered a different question, for example, “what are other things we could do instead of this proposal, or in addition to this proposal?”, then it is a faux objection.
