The I/O keynote always bothers me. Apple and AWS have great Keynotes that get me excited to develop on their platforms. Google's always comes across as too self congratulating.
Didn't you mean the opposite? Apple is always so self centered on their presentation that it is hard to watch.
Last time I watched wwdc they had staged a standing ovation for a trashcan...
They are just less polished in presentation. Which I like. Raw stuff is more interesting.
