I'm convinced LinkedIn demotes anything that links off-platform
Interesting...why do you think that? I was on LI the other day and it struck me that probably half my feed was "look at this thing on this other site". Admittedly, the link was usually under the fold in the comments, which maybe is a cheat code to get around some real or perceived blockage? Not that any sort of user-hostile behavior from LI would surprise me, I just made a mental note of it at the time.
I have not run a controlled study, but I have shared topics here on this website that made it to the front page quickly and had a lively comment section and on LinkedIn the same was had very limited impression numbers. I did an experiment with an ATLRUG announcement where I did not include the URL and the numbers were slightly higher than one that did, but still not great. I have connections on the platform with relevant interests but its not showing it to them.
One thing that has always hurt me is I have never once in my career been on the traditional job market. I was self employed as a teenager and have always just kept growing and pivoting and growing. I have never sought or taken a job via the normal market. LinkedIn has always been a bit of a odd place for that mode of work.
