Focussed on omega 3 from animal sources. ALA is the form in flaxseed and the like, and is explicitly called out as not addressed.
A reasonable point is made indirectly that eating fish may be better than taking supplements. I suspect in part it's because of oxidation and substitution in concentrate.
If interesting in Omega-3 benefits, I would suggest watching this video with Dr. Rhonda Patrick and Dr. Bill Harris who has researched fatty acids for over 40 years. [1]
