The perils of using Internet Explorer as your default browser

I have to side with wroot not everyone can switch. My company can't due to government sites that require IE, we cannot change this, they are not ours. We have to use them to conduct our business. I know some have mentioned Enterprise Mode, but that isn't a complete solution. We cannot use Edge on server, so what are we to do with our remote environment. We cannot expect users to use a different browser when using that environment than when they are on one of our physical PCs, then we are also back to having to remember which sites require "the blue e". The only way we can truly stop using IE is if these required sites get upgraded, which would be very welcome from me. However who is going to push this change? The state is certainly not going to listen to us telling them they need to spend a ton of money completely rebuilding them. Maybe Microsoft can start lobbying the banks and governments to finally catch up instead of whatever else they are wasting money on lobbying?
