Though yeah as a person who can't swallow pills that'd be a huge problem for me. I also know many many others like myself, so don't know how it'd proceed.
I once worked for a company that did the same - but with Lotus Notes, in 2013. Modified it into a full-fledged ticketing- and time-tracking tool. Using it took a half hour out of each workday.
I'm using Kodi since several years for the family TV. I only had to tinker with the streaming buffer for YouTube, other than that it required no maintenance.
My wife can use it from her mobile. We can play movies for our kids or stream a YouTube-clip. I'm using a Firefox-addon to cast clips from my browser to Kodi. That's about it, no killer app, just convenient digital media on an old, dumb TV.
Only I'd wish Yatse was ported to iOS (Unless my wife's iPhone dies soon).
Typing on my wife's iPhone SE is an ordeal for me, and I don't even have large hands. For me that's a reason why I prefer largish phones (I have a Pixel 3a, which is not that big).
This law is like having to provide and record ID when entering a concert, restaurant or other public places. It's an authoritarian dream, but will be shot down by courts, that's for sure.
As others have pointed out, the austrian government is populist right/far-right. This is not a law by centrist parties, but by right-wing authoritarian.
The case was never about anonymous hate-postings as the harasser's comments where posted under his real name, he just claimed that other people had access to his facebook-account. The case has been overruled by the higher instance a few weeks ago. I don't agree that this was the trigger for this law, the current gov consists of two right-populist parties/movements and made other irrational decisions in the past.
