assume Apple's motivation has something to do with product improvement or modification. Does it make any sense to base this on feedback that is largely meaningless?
if it leads to ill advised changes in Apple products that are based on misunderstood feedback.
With respect, I can't quite feature how these "Did this topic solve your issue?" buttons could possibly relate to Apple products (i.e., hardware and/or software), feedback on those products, or the modification or improvement of any Apple product other than Apple Discussions itself, which is a creation (or, product) of Apple Support. To think that all of a sudden Apple is going to "modify" or "improve" its hardware or software products by virtue of a generalized consensus of newb to middling computer users randomly pressing "yes" or "No" buttons here is, I think, beyond the realm of possibility (and even rationality).
Whether or not (or why) Apple Support would consider modifying, improving or just dispensing with Apple Discussions based on users' button pushes is probably a more salient question, though it is useless (and against the ToU) to discuss.
