With the new API of Instagram, 99% of the tools can not show any unfollowing data to a tool user since this information had to be removed from the services.
In my opinion, this is a perfect moment for unfollowing, since no user can notice that you didi it. An exeprion can be a professional acount with an expencive tracking tool, which saves all usernames. But a normal user with an usuall followers tracking tool won’t be able to notice that you unfollowed him.
Yes, you are right. I always unfollow everyone and don’t care if they unfollow me as well. Because a normal real user ( which I care about ) probably won’t notice me unfollowing him.
i know a lot of personal user who use Unfollower Apps 
Totally agree. I unfollow everyone and don’t care if they unfollow me. It’s not personal… it’s a numbers game.
Yeah, I guess some do care about the unfollows, some don’t…it’s just now you might keep a lot of followers due to the fact that people won’t be able to check this thing anymore…
