linkedin cares a lot about preventing people from changing how people view their website, and they have very effective DOM detection code which watches for manipulation like this. So if you use this extension it's very likely that your account will be shadowbanned, meaning you won't show up in searches (e.g. if you are a job seeker you'll stop getting cold outreach from recruiters), your posts will be less visible or invisible if you have any, and whatever other arbitrary restrictions linkedin's algorithm puts on your account which might even include stifling normal communication from your connections. And if you don't care about any of those things you might be better off without linkedin in the first place.
If that were true, wouldn't shadowbanning a worker, who entrusted the monopoly to be matched with job market opportunities, be arguable grounds for a lawsuit for great economic/existential harm?
Instead of this I use Leechblock to cut the /feed access after 2 minutes, to prevent doomscrolling (no DOM change)
Flagged for obvious BS with no factual basis.

Do you have any sources for this? (Even anecdotal such as conversations with people in the know)
I recently built myself a good tool that blocks all sponsored, promoted and recommended posts, and it's been incredible. This information if true would be a genuine concern!
