The person asking for another viewpoint has not promised to use it.

Being consulted is not the same as being obeyed. When someone asks what you think, they are gathering material for a decision that remains theirs, and treating your answer as an instruction they now owe you turns a question into a trap they will avoid setting again. Advice given with strings attached tends to stop being asked for.

Offer your view as clearly as you can and then let it go. Resist checking whether it was taken, and resist the small sting if it was not. If you find you cannot stay friendly when your suggestion is passed over, that is worth knowing before the next person asks.
