Is anyone aware of a LinkedIn mirror like xcancel.com for X?

Is that actually required?

I'm not at my computer right now, but as far as I remember most LinkedIn posts are viewable without logging in if you use the direct URLs, for example:

https://www.linkedin.com/feed/update/urn:li:ugcPost:

https://www.linkedin.com/feed/update/urn:li:activity:

Unless something changed recently, those links should work anonymously.

The best thing you can do with LinkedIn is delete your account and never look back. Horrible platform full of hot garbage and subpar for privacy.
