Fefe is quite the character (his coding style aside) and has done plenty of worthy projects. He's ostensibly quite controversial though for his ardent positions on minimalism, among other things. [1]
"You know that the Ariane 5 rocket crashed (and could have killed people!) because of an int overflow? What if people die because you decided the C standard allows you to optimize away other people's security checks?"
Sounds reasonable to me. As a security consultant, it's important for his work and his moral duty. Think of the children ;-)
That integer overflow is undefined in the standard also doesn't make it go away. Integers overflow everywhere. It simply means that the details of it are not part of the standard. The new behavior he's complaining about is not any more standards-conforming than the previous one.
I for one. There are fewer advertisements, most messages are just plain text and easily searchable, and I can receive and organize the data on my own terms. I still have mailing list posts I saved that are around 12 years old; every forum post I made over 10 years ago is gone from the face of the internet.
I still think nothing beats email for ubiquity and it allows the subscriber to consume and organize the content on his own terms (i.e. preferred email client, etc.)
GitHub issues, for me, is way better. You can opt-in and opt-out of notifications per thread, so you can drop out of something that turns into a total fracas.
I still get email notifications for things I'm subscribed to, or when I'm mentioned. It's exceptionally handy.
Subscribing to even a single mailing list tends to flood my email client with junk. Unless you go through the trouble of filtering these things, which is a total nightmare to do across multiple devices, you're just going to have to read through every single message.
