We'll see how long the feeds continue working for.
rsshub still seems to work.
Twitter's whole thing is its outsized cultural relevance for a rather small user base. If that goes, well, arguably, it's had its final day. This particular change seems like it might go a long way towards ending its relevance; an awful lot of people used twitter only via clicking links from news articles etc, and never actually had an account.

if twitter is dead to you, let it rot and die in the corner. free yourself from caring about its outcomes
E.g, despite it being dead since the redesign in 2010, you can still go to digg.com right now, create an account and all. Fark.com still exists. Slashdot still exists. None of these sites are relevant anymore though.
