I mean it did change for a very good reason. Stuff gets hacked because everyone is online always. In "the good old days" it wasn't a problem because people weren't really online so there was pretty much zero risk of old software being used to exploit your machine. These days? It's a liability to have old stuff on your phone because someone could exploit it to steal stuff from a large number of users.
That would probably be pretty hard, considering every service is different. Google drive stores your data and so their ToS probably says you can't store pirated content, but that wouldn't make sense for most other services that you can't upload stuff to.
Honestly the first one is the only one that works when people define the first day of the week differently. On the other hand, it does make you wonder. If Sunday is the first day of the week (as it is in many places) then how is it also part of the weekend?
Funny I recently had someone ask the same thing. This is pretty much the only route you can go. And 🏴☠️ sadly the only reliable one (if the software is popular enough)

It'll probably get you most of those features, though it probably won't be as nice as something purpose built. But if you already have Plex it might be nice to have all your stuff in one place. Alternatively you could probably setup something to download podcasts to your server into a folder that Plex watches.
Loads of stuff, I've pretty much been using InoReader since GoogleRss died, I probably used something in-between but I've been using it forever at this point.
For a while I used it for YouTube subscriptions, but I mostly use it for news and comics.
