You started with “not really” but then clarified that it does indeed change the costs to the worse to an unquantified fraction of its customers, so what you should have said is “yes really” both literally and figuratively.
Thus saying “not nessesarily” changes what? It’s like saying you’re wrong and then repeating what someone said.

Edit: how can something be “technically” true if the word has no definition?
That's still not true.
