Yes. I’m literally unable to read it without logging in to Twitter.

I don’t get this. There is no reason for anyone to have a Twitter account. It is awfully arrogant of Twitter to assume that anyone would want to sign up for an account just to read their users’ posts.

Is this sarcasm? This is their entire business model and how they get paid. I don't see it as any more arrogant than having to pay for a paper newspaper, digital article, or attending a conference

It is also awfully arrogant for stores to assume anyone would want to give them money for the things they are offering.

In what browser? I tried Chrome, Edge, and Firefox on Windows, and Chrome and Firefox on Android, all without being logged in, all without issue. I was able to view the full thread in each of those 5 situations.

I also tried Internet Explorer 11, but that genuinely froze my entire computer in its attempt to force me to load the page in Edge. I blame that more on IE than Twitter though.

Depends on the platform. Medium does the same.
