The OP has a right to post a scenario and seek advice.
The OP does not have the right to evaluate whether or not such advice is what OP desired to hear, OP does not have the right to post negative comments which, ultimately, work against the stated goal of obtaining advice/suggestions.
None of us (human beings) is perfect...few of us are willing to and capable of regurgitating responses which a given OP "expects."
That's how the forums operate...on a volunteer basis where members donate their time and energy...to try to provide something useful to a member obviously seeking "help".
If the OP wants answers in the manner that he/she might receive if paying someone to specifically troubleshoot an issue...I remind the OP that none of the members who respond to your or any other posted topics...are hired employees and they cannot be held to unknown "standards" that might be appropriate if the OP had taken his auto in for repairs and was dealing with a paid technician whose employment skills are certfifiable, respected, and usually incapable of being questioned by paying customers.
We have no paying customers here at BC...we have no employees. We have members who try to share and assist each other. None of them...may be "experts". Some of them...may be "experts" about some things. None are "expert" at everything. If someone makes a comments that you find...less than expert...the simple way of dealing with such here at BC (where many of us don't claim that our "answers" are THE ANSWER...is to just ignore the post and move on.
I suggest that you read the forum rules for a clear understanding of the basic things that are expected here...of all members.
