I happened to take a look at your HN profile and realized you don't post much, which leads me to believe this is REALLY bothering you.

I can relate. My grandfather, who had been a math teacher and actually got me into computing way back in the beige toaster Macintosh days, religiously checked his email and practiced his Spanish on Rosetta Stone for decades. I had to update from Win 7 to 10 for the desktop I built for him, and that was a big struggle for him. That would probably be many times harder now considering the sad shape of Windows. It was heartbreaking watching him struggle with one of the few simple joys he had left towards the end of his life.

I'm very sorry you're having to deal with that and your anger is warranted.
