DebConf does host their own HLS streams. (They use video.js, which was started by the cofounders of my former employer Mux; I'm pretty familiar with it.)
I don't intend to suggest that it's impossible by any means; I've done it recently for a project of my own. But it's work, and it's expensive work, and it becomes a question of quality of experience. They make compromises to do their own hosting; bandwidth is always a little bit scarce and DebConf's live streams are 2Mbps @ 720p as a max rendition. For their audience, that might be fine. For others, it's not, and a good way to drive viewers away. I don't have an intuition as to whether the EFF's target audience feels that way, but their overlap with the free-software set isn't complete and wanting their live streams to look roughly competitive with everybody else's isn't unreasonable; how you look and the reliability/QoE of your stream does impact credibility.
The second tine of the fork is user accessibility. "It's just Twitch, everybody uses this" is a powerful argument for that accessibility if, unlike DebConf, you can't reasonably expect everybody to read a man page if there are problems.
