What evidence do you have that people present in the church during the filming of the miming of a protest song were actually offended?

Puzzled would be more likely.

(If your evidence is limited to what was reported of what witnesses said in court, and you believe it, then... well I have a business proposition for you concerning a bridge)

And what is your evidence that "PR didn't hit whom they pretend to have targeted"? I rather thing the Stalinist-style show trial is strong evidence that they hit the intended target pretty hard. i.e Putin and the Patriarch were stung by the insults proffered.
