I appreciated how the reddit app I used (relay) kept everything internal. I don’t want all the links I open on this app opening in my browser and plugging up my history. I doubly appreciated how it would open YouTube links in an internal video player that wasn’t linked to my YouTube account in any way. This is a must have for me to prevent my YouTube “algorithm” from getting any ideas. For example, I watch a video about “X” and now my whole feed is suggesting I watch more videos about whatever “X” was.
There’s nothing stopping anybody from opening a yt link in am external browser in relay. I just like the convinience of keeping everything in one app and keeping WHT I look at in reddit separate from what I look at kn YouTube.
