There is 'core' and there is 'classic'. And there are good/bad arguments for both. That ship has sailed.
Now there is a new problem. With Blockstream's takeover of core and eviction of Gavin - it is time to fork the Git as follows:
Make an IDENTICAL copy of core. No changes whatever, core1 and core2 - not one line of code being different. Start a new Git with new people (non Blockstream) having commit access. Put Andreas - seemingly the only clear thinking reasonable guy these days - on with the highest credential. Get others - on both sides of the aisle - to join too. Then, minors switch to core2.
Theymos' censorship and Blockstream's takeover of core are bad for Bitcoin and bad for our future. We've got to undo this now. We can settle the blocksize debate later. Now, we have to stop the takeover of Bitcoin by this clearly corrupt private entity.
