I have been (forced against my better judgement) to attend a total of 4 conferences in my whole career ... and been politely asked to leave during 3 of them<p>In all cases, my questions were perfectly valid and reasonable, but this was at a time when &quot;linux&quot; was considered some sort of nutjob conspiracy theory that would go away if ignored.<p>I think that the total amount of unemployment I have had over all those years adds up to about 2 weeks total ... plus the additional inconvenience of spending about 4 months total in court. (which I managed to successfully bill for, so I suppose that doesnt count.)<p>The various CIOs, CEOs and other &quot;Eye Tee&quot; experts that I met at these conferences - Hopefully - are no longer involved in the tech industry.<p>Just sayin ...
