Character attacks on the internet are self defeating and foolish in many ways. There are little to no stakes for the attacker if wrong (undermines the value of the attack). The attacker is being hostile to someone completely, or mostly, unknown/unfamiliar (foolish). The attack does nothing to address the actual argument/points being made (waste of time for readers).
Rather than oppose the messenger, perhaps lead with opposing the message itself. It is far less hostile and is more productive. You will get better at countering the argument/points if you actively practice doing it, and it is better for everyone involved (more focus on the issue rather than the winning a battle against someone "bad"). You also might spare yourself counter takedowns like you got here, this one being particularly spicy.
The article linked doesn't even seem to say that microservices are always bad. It simply says they are difficult to do, and the author sees them as over engineering. Overall a pretty common opinion.
