This is the one redeeming quality of Meet, and it's worth a lot. I can click on a link that was sent to me and all the essential videoconferencing stuff will just work in my browser. Also in Firefox, regardless of what sibling says (I use it regularly on Linux and macOS).
This is a technical feat that somehiw still escapes most of the other videoconferencing platforms (except maybe Zoom, but then they try to hide it as much as possible).
I have personal witnessed this happening with Wind-Infostrada in Italy. DNS spoofing was done through the ISP provided fiber modem/router though, not at the ISP level; if you actually changed the DNS servers on the router than it would send all your queries to those routers instead of the ISP ones.
I couldn't figure out if this was plain incompetency, an attempt to enforce DNS-based website blocking, or some programmer willfully implementing the latter with the former so that it would be reasonably easy to circumvent.
Also Italian residential providers really, really like to mess with NXDOMAIN instead returning a helpful error page with affiliate links instead. You might think you can imagine how much shit this breaks; you probably don't.
While the problems with templates and huge includes are undeniable, I've found in my experience that for a decently size C++ program the linking stage alone can take way more than the 3-4 seconds the GP is talking about.
C and C++ are definitely some hard beasts to compile, even without boost.
