I'm using Firefox and Brave on Linux from a residential internet provider in Europe and the 429 error triggers consistantly on both browsers. Not sure I would consider my setup questionable considering their target audience.
Then it means they're looking at the User-Agent string and determining that an iPhone in Europe most likely has a human using it, and might not require rate-limiting.
IMHO this would be a huge mistake by RedNote. From what I've seen, the more people learn about their Chinese peers the more they realize they've been seriously mislead by western sources about what the people, culture, and conditions are like. This has been a boon for anti-US/pro-China PR that the CCP could only have dreamed about.
I self host freshrss (https://www.freshrss.org/), super easy to set up via docker and it doesn't required some over provisioned dependency setup (DB servers, etc...). It has nice/familiar keyboard shortcuts and a clean and fast interface. My only complaint is that the cloudflare-ifiation (aka enshittification) that is slowly ruining and rotting the internet prevents the fetching of RSS feeds from some news sites from your presumably affordable non hyperscaler VPS instance.
When using mobile I use https://capyreader.com/ which has first class intigration with freshrss; meaning you can add/remove/view feeds via the app and have the changes sync with freshrss. Also, probably my favorite feature of capy reader, is that when you want to view the content of an rss article that is only a summary or headline (because few people publish the full content of their articles in the rss feed anymore), you can just press a button and it will fetch it for you and display it in the reader without sending you to a browser. So much happier and more accurately informed since moving back to RSS where I can choose what I want to see vs having it filtered/fed to me via some biased algorithm.
I use the freshrss web interface on my phone, that works quite well I feel. The app might not be necessary.
BTW, Freshrss also has a function to fetch the full article content directly. I think it's not especially clever, just uses a selector, but worked well for me for the one or two feeds where I enabled it.
Oh nice! I didn't know that FreshRSS could do that via the web app, that was pretty much the only reason I used the capy reader app. I'll have to test it out, thanks!
