I didn't feel at all like he was disappointed in his viewers, he seemed more confused or even worried (which is a valid concern given it's his work) that people may not be interested in the kind of content he thought they were, and asked for some feedback on the matter.
I am fairly new to subscribe (only done so a few months), since I just really didn't do that with anything on youtube until recently, but I now usually watch most of the "WTF is" and "Content Patch" videos as I enjoy TB's style of commenting and I find that content relevant for me as a PC gamer primarily.
I do feel he kind of forgot to consider easter and holidays as a possible reason for the low and/or slow views on a lot of the Pax videos, it's been a factor for me at least. Updates were slow due to Pax, which I knew he was attending, before my own holidays started, so I didn't watch any videos or checked for updates during this time. When I return so much stuff has gone up + the normal content schedule has returned as well, and knowing these videos aren't gonna quick ones, I've had to take my time.
