As far as I am concerned, all your points are valid and well articulated. I am sure other posters find them useful as well: this is a discussion forum and if we all agreed with each other it wouldn't be fun and the learning opportunities would be far less.
If FIH is a big position for you, you should definitely attend the AGM and voice your concerns, just don't go there with the expectation to hear the answers YOU want.
I understand your frustration but there's not much the COBF can do, just sell it and be "psychologically short" a la Ackman.
FWIW, I sized the position taking into account positives and the negatives and I am not in love with the stock: if the upside materializes great (I might trim it, keep it at 5% and redeploy proceeds elsewhere), if not I'll just sell and move on without losing money and a second of sleep.
3 years ago I bought VW and Porsche Holding thinking there was 4x upside, limited downside thanks big cash balances and a family willing to surface value through buybacks, spinoffs, costs cuts and dividends. I lost 50% but the position was sized appropriately and didn't impact returns too much. I took the loss, learned my lessons and bought other stuff.
I encourage you to keep posting your analysis and discuss ideas. Just keep a joyful and playful attitude, we are blessed to be able to do this!
Best,
