There is a line between advice and instruction.
Advice can come from anyone at any time on any topic. It can be followed, taken under consideration, modified or ignored. It is not the final word on a topic. It is a suggestion. Granted the person giving the advice most likely would prefer that it was followed, but in the long run, it is still just a suggestion.
Instruction are orders. They are issued from a person who has a perceived level of power over another and are expected to be followed, typically without question. The level of power can be anything, including “this person has something I want, and the only way to get it is through them” to “this person has some level of control over my actions”. Instructions, though they have the ability to be changed by the issuer, are not expected to be modified or ignored and if they are, there may be consequences, such as not they reaching the desired result.
If given advice, it is the responsibility of the person receiving the advice to decide what is best for them. The intentions of the adviser may lie in the best interests of the recipient, but ultimately, the recipient needs to be able to judge on their own the appropriate course of action. Otherwise, that person winds up a lemming who blindly follows others.
When given an instruction, the consequences of ignoring the instructions lie solely on the recipient of the instructions. That is one of the reasons why we have things like EULA clauses, to protect the party that has given the instruction from liability should something go awry from their instructions not being followed to the letter. Yet again though, the level of personal responsibility exists.
No matter what is said to me, I am responsible for my own actions. If I make a bad decision, whether it was due to instructions or advice is immaterial. I am the one who chose to do it, either because I wanted to, because I thought it was a good idea at the time, or maybe because I was short-sighted and did not see long-term consequences. Though it would be nice to say that someone else told me to do it, that person does not necessarily have to live with the aftermath.
The adviser or instructor has a responsibility too, but it is for their own actions, products, instructions and advice. When driving a car, if the passenger shouts “turn right now!” and I turn immediately and crash into a brick wall, the passenger can ask “why did you turn into a wall? Didn’t you see it?” My response of “You told me to turn right now” will probably be met with “Common sense should have told you to turn where it was safe”. The same principle applies for me whether I am given advice or instructions. I have to be able to determine if what I am told is detrimental or beneficial to me.
Ultimately, responsibility for myself and my actions lie with me. I am accountable for all the decisions I have made, be they good, bad or indifferent. I have listened to advice, I have taken orders, but when it comes down to it, at the end of the day, all of the choices were mine. I have made plenty of mistakes, I have followed bad advice/instruction, I have ignored good advice/instruction. I do not blame the advisers or instructors for the consequences, I feel that responsibility for my actions is all mine.
