While some people were too busy cheering the death of plugins, they were being bought back to life thanks to the rejuvenating powers of WebAssembly and WebGL.
All of them already have some kind of support in WebAssembly.
Still, overall better than the situation of having to install a plugin that may or may not be available or working fully on your system. Plus security concerns of running sometimes obscure binaries on your system to access web content.
I'm aware it's not impossible to exploit the current plug-in free browsers we have now. It's still objectively better than before.
Not that I'm satisfied with the current state of browsers mind you. I just think not being forced to install someone's binary blob to look at web content is a net benefit.
