Aside from political or social reasons, X is a terrible platform.
More often than not, I get a blank page, something didn't load.
If I get content, it's (randomly) behind a registration-wall.
Or it shows confusing cookie banners that half the time don't even work. (Dev console full of js errors)
So I don't even bother anymore. This service is technically so fragile and unstable, it's not worth the click.
Aside from how it's socially and businesswise broken. Because I have looked into some of the errors and issues and they'll only occur for "anonymous users" and not for twitter users. They're oftencaused by (normal vanilla) adblockers or privacy protection.
So I dare say they're either malicious, deliberate. Or lack of interest/resources for non-registered and/or privacy-aware users
I don’t see any similar attempts to transparently live fact check on any other platform.
