> Not a single tx has been reverted on BTC network in 13 years (well, except of couple of early bugs that caused network split)
The article mentions that the networks tends towards centralization, at which point the guarantees BTC was supposed to provide no longer hold. You can say that the big miners still won't do it for $REASON, but the point stands that it's not irreversible nor uncensorable, due to this centralization.
> No one is able to prevent a tx from going out, as we just witnessed - FBI wasn't able to revert a $3.6B theft transaction without getting hold of private keys.
The money stolen is not relevant, the budget they were willing to spend to retrieve the funds is. I don't think this was in the billions as you implicitly state. Preventing the transaction from being mined is also completely different from reverting it several blocks after it has been mined.

> I paid a tx fee once, two years ago, to fund my Satoshi Wallet, and haven't paid another satoshi in tx fees for about a hundred of purchases since then.
According to https://en.wikipedia.org/wiki/Lightning_Network#Limitations you still need a "watchtower" to ensure things won't go wrong, so if you consider everything, it's not completely free. I don't want to guess what the exact price will be because it's a futile exercise (we'll see soon enough if it gains traction), but this suffices to show that you're sweeping some costs under the rug.
