"The developers" do not exist. You mean the core project which has it's own developers. Their work may be adopted, but that is a consensus issue and is not their decision. Anyone with an idea to improve bitcoin is welcome to write code and let the bitcoin community make their choice about it's merit. So for me there is no conflict of interest because they do not represent bitcoin, they only represent themselves.
How can they serve two masters at the same time? Is it not obvious that they working for Blockstream and at the same time holding back on upgrading
the Block size to pave the way for SegWit & LN? You cannot throttle something and then suggest a solution to make it faster, if people accept your
solution.
.... I know these are some of the best developers we have at the moment, but I to think there is some conflict of interest here.
