If they didn't think there was a fee problem they wouldn't be working on segwit/LN implementation.
I went looking for a roadmap for BU today and what I found was a seven months old, very weak regarding the current issues, and and vague about the proposals it did have. This is not a serious alternative to core/segwit/LN. Hating on core without evidence they are doing anything wrong is not going to fix anything.
If I had a miner I'd be doing exactly what the folks on Reddit are doing - signalling support for BU so they go ahead with their plans, then pull the rug out from under them once they commit. It's time to end this foolishness.
simple solutions dont require big re-writes
real workable solutions dont need excuses of why X, Y, X are needed . then downplaying it when its revealed that X and Y are not needed and Z is actually an A(complete opposite)
simple solutions don't need to promise things and then pretend the promises still promise even when it wont be achieved even if they got super majority
simple solutions dont need to suck eggs and write scripts with buzzword of the month competitions to show which spammers are involved in the competition (like a secret handshake)(bucoin btucoin, ad-hom, conservative)
