I don't understand what's that

I assumed they were talking about 5ghz WiFi, thogh that might not have been the case

I'm guessing they probably meant something among the lines of the four Rs: Reduce, reuse, recycle and repair.

I believe that it is about reducing the amount of waste, programmed and perceived obsolescence as well as making electronic devices easier to repair.

Do note that people will still use chrome and ignore the problems
