I think a bit is being missed in twitter largely due to space. I think what Hadi is trying to point out is the priorities associated.

Let's propose for a moment that we are a conference of 1000 people @ $400 each with 80 speakers (some will be local etc). From the rates discussed let's calculate quickly what T&E would come to 80*300 + 160*2*80 so 620 each over existing. If we were to do a quick calculation that comes out to roughly 50k.

I believe what Hadi was pointing out is that the conference has prioritized lower prices for attendees over paying T&E for speakers amortized over 1000 people the difference is rather insignificant from a ticket price POV ($50/ticket). Even if the numbers were a bit lower for attendees and the count lower with higher T&E it could be said that a 20% price increase could rather easily cover it (and 25% would double the hypothetical numbers above)

If this is not done there is a rather significant "donation" being made to a conference from the speakers. Not many speakers are wi
