I think junior and intermediate developers get a lot more noise from recruiters as they form the bulk of the dev community. Recruiters are just in a frenzy to stack the ranks, where with more senior roles you have less positions to fill and the talent pool is even smaller... and I dare say most of the higher positions are filled via connections/nepotism etc and not using recruiters to bulk-fill.

Most of the devs I know have never used any recruiting companies, since they are not required to "get in the door" in my country. Its just not part of the culture. I personally have used one once, about 5 years ago as an experiment... I'm still at the same company, so there's that. I don't have linkedin. I had an account many years ago but it was spammy and wasting my time so deleted that account and have never been back on it.
