Unfortunately, everyone who provides these big feeds (Reddit, Twitter, et al.) don't like that their content is being filtered by third parties and clients. Because they want to keep their users on their platform as long as possible, and their algorithms are designed for it. So they actively make it very difficult to do so, by banning these clients.
On Instagram, you can't even fast forward videos because of that. They want you to watch them fully.
We really need clients for "feed of feeds", but how can we do that if we don't have access to the feeds? The browser could be a solution, but pages needs to be filtered based on the source code of the page, individually.
