Which yeah, doesn't mean absolutely anything for existing software that is still working and requires the old version to run. If by any chanche you need to support that configuration, the "official" deprecation simply means "good luck!" and a pat on the back.
Just like XP, I've seen plenty of shops with custom software that still requires XP+IE6+activex that still get active development, because a total rewrite is out of the question when changes are small (and that is totally understandable as well).
The poor folks though will need to containerize and isolate everything from any network though to keep it somewhat safer. If they do that at all.
IEMode in Edge also works very well
So if these companies are getting windows updates at all, or edge updates at all is somewhat not optional
The funny part is the app they use still works, you're just forced to run it in compatibility mode on Edge (Holy, I forgot this existed) but their user profiles have limited access so they can't right-click, properties, unless they have admin priv.
New browser, same old 2009 problems. Obviously this is not the browsers fault, it's just insane to hear about shops like this that still hold on to legacy apps FOREVER.
Bosses never want to spend a cent, because of the "shareholders". They also don't want to say "yes" to something because if there is an issue, it is then their fault even if it was worth doing. They would rather kick the can down the road until the wheels come flying off the car.
This is why nothing ever gets updated.
IT: Well IE is end of life so we need to Spend X to upgrade
That is an IT reason, not a Business Reason.
It needs to be put into a BUSINESS reason, and I admit I am terrible at that as well
