Twitter made a change to their API on July 25th that prevents very useful 3rd party tools from scraping accounts and turning them into RSS for self-hosted feed readers like RSS Owl to consume.

"2019-07-25: Twitter have changed their UI. For now, user queries should continue to work, as they'll be directed to the mobile version of Twitter. Search queries not so much.
2018-10-17: Twitter are rate limiting requests from TwitRSS.me, meaning it is effectively broken until I can think of a way round it. You can still run your own instance"

It's obvious that Twitter's instrumentation wants to know (via cookies, browser fingerprint, IP address, etc.) WHO is accessing each tweet, whether or not they're using a Twitter app and whether or not they're a logged-in Twitter user.
By using the aggregator site and presenting all the tweets in an RSS feed reader app, people like me were somewhat anonymized and able to consume a lot of twitter without touching twitter's website.
Can't anymore. Had to delete all the feeds from my feed reader that were utilizing twitrss.me to convert from twitter handles to RSS.
Can still consume RSS feeds that are generated by various news websites.
RSS was a great idea. I think websites hate it because it enables people to take their published content and display it (or just headlines & URLs -- how much content appears in an RSS feed varies widely from headlines & URLs to 1 graphic to full articles) in a different format without giving the publisher any "eyeballs".
