FWIW,
InPractise is publishing a series of interviews about Fairfax, e.g. https://inpractise.com/articles/fairfax-financial-retail-subsidiaries-perspective. You need a subscription, unfortunately.
I think they do a great job, focusing on quality/compounders and their research is deep, more curated than Tegus or others. They work with "alligned" fund managers, mostly long only, long term oriented...
Best,
