Device owners are advised to update systems as soon as time permits.
How about throw it in the trashcan and buy a new one from a more trustworthy manufacturer? This is totally unacceptable!
Just like HTTP/2, HTTP/3 is a protocol by Google, for Google. If you are not a big company like Google, you won't benefit much from it. The web was simple, now it will be complex and ugly. Many ordinary websites don't benefit from all the features in HTTP/2 or 3. What Google should have done, is leave HTTP alone and create their own protocol via WebSockets. They could even have a more optimized protocol for all their Google webservices.
Yes, HTTP/1 was old and could use an update. But it could have been much more simple, that was more easy to implement for both webbrowsers, webservers and webproxies. One thing that was simple to do was to enable request pipelining. Most webservers and browsers already supported it, but it was disabled by default due to some crappy webproxies. And instead of fixing the webproxies, we switched to an entire new protocol. It doesn't make sense to me.
