What he means is that they would announce things in the past in a more definitive way, then people would get their expectations all in a tizzy, which was a bit problematic when things were deleted or changed. And now, because of the internet, people are much more aware of what is announced, in detail, than they were previously.
As a result, there's so much hedging *precisely* so that if something doesn't work out, they can say "well, technically we never said we were going to do that DEFINITIVELY; the problem wasn't that we promised you something and didn't build it. No, the problem is you, the consumer, reading into it too much."
