Whilst it was simultaneously compelling/farcical/excruciating to watch the 'big-four' tech CEO's grilled by Washington lawmakers, I couldn't help but feel - at times - it resembled a 'kangaroo court'...

If you took a look out of the 'Windows', you'd ask why Satya Nadella (MSFT) was not there?... last time I looked they had a market cap. of $1.5TN. This was, after-all, an inquiry into tech firms exploiting their size for unfair competitive advantage.

Personally, I think they are missing the point - there won't be a level playing-field, until large corporates are prevented from using numerous off-shore tax havens and loop-holes. This problem is not specific to the tech industry.

Anyway, for what it's worth, here's my 'rate card':

- Zuck (FB) is 'battle hardened' - can wriggle out of virtually any question

- Bezos (AMZN) fell into a couple of - obvious - traps

- Pichai (GOOG) at times looked rattled

- Cook (APPL)... I doubt his heart rate/blood pressure moved at any point

If they really wanted to put a 'cat amongst the pigeons', they should let people who inherantly understand the tech industry ask the questions... say, the likes of Peter Thiel and Elon Musk... now THAT would be 'box-office' ;-)
