These websites you found are definitely using RSS incorrectly. My website's RSS feed displays the full article, upload date, and author. I think their website's HTML is either scuffed, or they want you to visit their website, which doesn't make any sense?? I think their HTML semantics are just messed up. When coding a website (Which almost nobody wants to do these days), you are supposed to wrap your blog post content in an "article" tag, something that a lot of website builders don't do at all. This tag's contents is supposed to be able to make sense on its own - in this case, a standalone blog post without having to load the rest of the website.
Winboat allows you to run Adobe software as if it was a native app on Linux. Or you can just use a virtual machine. There's really no excuse not to use Linux anymore. I personally use Lutris for my non-Steam games, and other Windows programs.
My parents are not MAGA (They are more "centre-left"), but I do feel very sorry for anyone who has to deal with parents like that. I have other family members who support MAGA, and I simply don't talk to them, because I cannot look them in their eyes, knowing that they support pure evil. Their Facebook profiles make my blood boil, but I try my best just to watch the meme my father sent me, so I can carry on with my day, without it being ruined by my Neo-Nazi fascist family members. We aren't even American, but you know the saying by now - "When America sneezes, the whole world catches a cold".
