We are talking about one very specific issue, the point of this thread is a joke about new and delete. And your response after evidence services against your position is, “what about all these other things?” Definition of whataboutism.
Nope, the whole issue is about modern C++ in practice versus slideware at conferences.
Also chromium code base is one example from many others, and it is so modern C++ that Google has finally decided to adopt Rust as only viable alternative to improving it.
Big G has plenty of samples that aren't so modern, specially on Android. Which by the way is also moving away from C++ instead of "modernising" it.
