Well, it was more to recognize that there is no inherently better programming languages in theory, they all do the same stuff. And some languages are "better" at some stuff just due to the libraries available and nothing to do with the language itself. But yea I do think Rust is an objectively better language than C++.

Of course, but it still makes sense to think carefully about the advantages of disadvantages of the tools you use when starting any project.

Not everyone with the knowledge to identify this mistake is in a position to personally correct it. Do you have the time and resources to personally build a browser from scratch? No? Why do you assume a random commenter does?

It doesn't change the fact that Rust is similarly performant and much safer and will thus be faster to develop and less bug-prone. It's not a difficult assessment to make. If you want to explain why they're wrong you can talk about the issue on its merits, but you didn't choose to, presumably because you can't.

If were just a personal project that they're building entirely on their own then sure, go nuts and do whatever you want. But they're trying to gain adoption, asking for contribution, and wanting to replace other browsers. At that point it's no longer just a personal choice if you're asking the community to invest their time and money into it with you

The Rust Foundation very deliberately does not control the development of Rust. There has been issues with the moderation team in the past but I think they're actually resolved today. And let me just assure you that Rust is not the only language project with problems and the fact that they have been talked about and discussed in the open and resolved is a sign of maturity and trust, not a bad thing.
