BU is a very boring mechanical solution to the problem.  Nothing mysterious about big blocks.  

SegWit conversely is 'slight of hand' and 'magic trick'.  It is MORE data, not less data.  Just because you move some data behind smoke and mirrors, doesn't somehow make a reduction in transaction weight.  

SegWit is an altcoin.  SegWit is promoted by hooligans who are actively trying to merge the network into their own proprietary system (Lightning).  

The OP is nothing more than a paid shill.

I support BU.  Hope you will too.
