I tend not to attend any talk where I recognize the name of the speaker's company. Two-pizza teams from giant companies often have talks that either were only prototypes, or were actually tire fires in production, or will soon be shuttered. They can't give you the straight talk because it might embarrass the company/team.

If it's a big conference and the speaker is from a no-name or I don't recognize them, I expect the talk was accepted because it's actually an interesting talk and not just coming from a big name company or a sponsor. I also get a lot more out of non-technical talks.
