I learned to fly — and spent a bunch of years subsequent to that — at Oakland, CA (KOAK), and just took flight following (and the rest of ATC) for granted. It was the default, even (especially!) for local sightseeing flights, and I was always glad it was there and happy to use it. Even after moving to Hayward (KHWD) a few miles from Oakland, I used it for almost every VFR flight I made — I just couldn't see any down side (and still can't in an airspace like the Bay Area's). I've experienced very few of your downsides, but then maybe it's because my flying has been entirely on the Left Coast (SF and LA, mostly), and passengers often actually like hearing ATC (and I always brief them on my rather ruthless approach to cutting passengers off mid-conversation when ATC calls).
Anyway, I liked your video — very reasonable and balanced, and it's difficult to imagine anyone taking too much exception to anything in it (but this is the GA community, famously full of experts on everything...). Plus it's nicely produced and laid back, in ways that just aren't so common in the GA video world.
