Remember that its not your place to guide/suggest/teach to start with?

1. You're in the same match, i.e. similar MMR. You're just as bad as each other. The sooner you accept this, the better off you'll be.
2. You may be open to advice, but they may not. Most people don't like being given advice. Focus on your own improvement, not theirs.

Technical knowledge means jack squat if you don't have the mechanical skills to back it up. I'm a perfect example of this - over 10 years of playing DotA, 8 of which were a mix of competing and coaching. The end result - an MMR of 4k. My ex-WCG mates have roughly the same rating as well. Your MMR is a measure of consistency, nothing more.
This is a forum, so you're free to share etc. People come here to ask questions, hence they're generally more open to receiving comments/advice/criticism. In-game however, I find this to be quite the opposite. People hate being told what to do, even if it's nothing more than a mild suggestion. If you need proof of this in action, try play 10 games where you just mute everyone else the second the game starts. Understand that you may have good intentions, but the individual response to it varies. It goes without saying that the majority of the player base in this region behaves like an autistic teenager with rage issues.

Here's my rant.....

“Think for yourself and let others enjoy the privilege of doing so too.”

My pub teammates owe me nothing, likewise i owe them nothing. They have no right to tell me how to play my game. Listening to random teammates is the worst thing you can do if you want to improve. 99.9% of them are wrong, their advice doesn't make any sense. They overestimate their understanding of the game. They don't respect their opponent intelligence. They think they're the only one who's capable of making logical decision.

When i watch tournament broadcast, those commentators annoy me. Why?, because they don't have a f***ing clue about the game. Most of the time, their game analysis are plain wrong. Random advice from pub teammates? Please..... don't...... even......

Of course i try to communicate and relay information to my teammates during the game. I won't force it if they don't want to listen, because i expect the same treatment from them. Sometimes what might seems common sense to you seems absurd to others. That what i meant when i said we need to tolerate each other.

I remember one game where i play mid, this one support can't stop b****ing about me. It happened when he rotated to mid, he then pinged me to kill opponent mid. I ignored him, and because of that he flamed and mocked me throughout the game. Well i can understand him, because at first glance it might seem like a free kill. He was probably so frustrated, he can't understand why this mid player ignored such an obvious free kill.

It was a free kill btw, anyone in his position would get frustrated too. But here's my reasoning for ignoring him; i see both support missing from our opponent safelane. I decided to respect our opponent and not gamble on the kill. We could have gone and killed that mid and escaped without a scratch, but that's not my style. Never ever disrespect your opponent. In that situation right or wrong is just a matter of perspective. People tend to judge who's right or wrong based on result. Our difference in mmr? almost 1000.

Think again, would people listen and watch that video if its not Aui_2000, but some random dota player on the internet? Probably not. I've seen Meracle, Yamateh and Jed getting flamed by their entire teammates in pub. Did you know that Jed a 7k player gets verbally abused by his pub teammates on frequent basis? Why? because everybody think they're entitled to express their opinion, and anyone who disagrees will be branded as someone who can't be criticized. When 4 players who're clearly on the wrong side disagree with you, not even your 10k mmr will save you from the flame/abuse.
