So if he is interested, then maybe ordinals aren't completely useless.

The problem with the Ordinals Attack has never been its uselessness. The problem is that it is treating Bitcoin, aka a payment system, as a cloud storage.

Can you say DNS is useless? No. But storing it in bitcoin blockchain is problematic. This is why Satoshi and anybody who understands Bitcoin is against such things.

This way you could host your PGP keys or something like that in a decentralized network instead of depending on some servers that can be seized, compromised or otherwise tampered with.

They also mentioned an idea of using LN payments to stop spam email, fake accounts running crypto scams and so on, by using micropayments.

That's not a solution though. When we are talking about Github, it is not just about fake accounts and PGP keys. We are talking about a platform where code is being shared with its version control system (git), changes/issues/pull-requests are being shared and reviewed publicly, and a lot more features.

To get rid of that centralization, we need a decentralized platform that offers all of this not just a place to store PGP keys.
Not to mention that storing PGP keys inside a transaction does NOT solve anything whatsoever. It is just as arbitrary data and an attack on Bitcoin as any other Ordinals transaction. PGP relies on Web of Trust not on where the key is stored.
