This is what the policy says:
"If you had a temporary residence permit (a B permit) before you got a continuous residence permit, a half of the time you lived in Finland with a temporary residence permit is included in your period of residence. In such a case, you need to have had a continuous residence permit (an A permit) for at least one year immediately before the Finnish Immigration Service makes a decision on your citizenship application. The time you have lived in Finland with a temporary residence permit (the B permit) can only be included in your continuous period of residence."

And this has been the practice so far and these citizenship threads on this platform alone have tons of examples verifying the same.
I am not sure what was the ylitarkistaja high on when he/she discussed that with you. Laws have universal application, it is not possible that they apply it on one case and refuse to apply it on your case. They can clearly be taken to court if you have a written reply of the sort you claim to have which I highly and humbly doubt based upon the numerous similar claims you've made earlier.
Copy-pasting some of your similar claims below that I could quickly come up with a cursory search.

I have got an info today but I cannot say if it’s true or false. So don’t blame me.
According to that info, Migri has 4 queues for citizenship applications:
2- Middle East, Africa (Turkey, Azerbaijan and Iran included here)
4- EU and USA
Fastest queue is Russian, slowest Middle East-Africa. And processing time checker and kamu is symbolic (mandatory for Migri according to law).

"The thing is that, when I contacted migri several times, they made it clear that there are 2 queues only. 1 basically for refugees and asylum seekers and other for the rest of the applicants. And also stage 1 (waiting for processing) means nobody has touched your application since you proved your identity. This is also something that migri told me."
