Did what my friend said somehow right? Is high transaction fee extortion?
Some people will say that the more money miners see the more they will want to increase their hash rate and the stronger the blockchain.
What is happening in the mempool now calls for concern, a lot of people who would have easily adopted Bitcoin will be wary of it due to this development, this is as business transactions will prefer to use other alternative coins/tokens. This is happening already, which is why I implore the miners and the developers to come to a reasonable conclusion that will be for the common good of all and not for their selfish interests. Fine, miners would want to make money, but Satoshi wouldn't want the money to be made in the exploitative way we see now. And I can't blame the miners, I blame the system which causes the monopoly in which miners can do whatever they like without anyone cautioning them.
We know human beings, it is business as usual for them when they see the opportunity, and if there is no restriction to compel them to do the needful, they will continue like that. This is simply because they don't care about "Bitcoin" as a whole but care about their pockets. Well, as it is now, I believe that the developers must still do something, and this time, it must be a lasting solution that will curb the monopoly in the mempool and block mining. There are brains among these guys but I believe they are not doing anything yet possibly because their hands are tied due to the miner's voting dominance. Miners have kinda of hijacked the system now in the guise of Ordinals and BRC-20, all that seems to profit them more. They should vote for a solution if they truly want Bitcoin's transaction to be welcoming to users.
As for your friend, so far he is not deeply rooted in Bitcoin, you can't blame him and I don't expect anyone to. Imagine if he used Litecoin, maybe a $0.007 fee at times would have delivered the same amount. Now, compare it to the $10 deducted from his money, it looks exploitative.
