The key to making the feed more tolerable from an advertisement perspective is to methodically remove all the "interests" they've collected about you:

https://www.facebook.com/ads/preferences/

Advertisers buy into Facebook's ontology in order to target the ads. If you have no interests you'll likely not get targeted. Very few advertisers reach out to generic "male in their 30s", etc.

Then turn of all the other setting such as "Ads based on data from partners", etc.
