I am not wrong in saying that the Lighting network is being developed by Blockstream, and that segwit arbitrarily favors this transaction type for this technology over other transaction types, call it a subsidy if you will.
Your post made it seem like Blockstream is the only one behind Lightning Network (and implied control). You should watch your wording then.
Even if Blockstream is benign, the conflict of interest is clear. Just another example of Core attempting to apply a centrally planned economic policy onto the Bitcoin protocol.
As has already been demonstrated a number of times, Bitcoin does not scale efficiently via the block size limit. Bitcoin was never and will never be suited for microtransactions. These two things you can't change unless you redesign Bitcoin from scratch (obviously not possible anymore; you can create a new coin though). The only way that Bitcoin could ever acquire mainstream adoption would be with the use of second layer solutions such as LN.
