Constructive criticism have 2 party involve
1 someone give a constructive criticism
2 someobe receive it.
When the 2 party involve act like a responsible person, a constructive criticism is supose to strengthen a bond.
But even with god constructive criticism, if the receiving party don't act and respond to it, it is going to degrade the situation and the bond.
This is not my personal opinion, this actualy how the process is suppose to happen to work.
Go read any source about constructive criticism, Asking people to give positive criticism without answering it the proper way become automatically a negative process.
The way ea is not answering criticism cannot be a positive process.
The last step of such process is always call follow up. After having some time so think about, the person answer the criticism. Right now, ea is trying to do this process without having to do a follow up, so the process still incomplete.
