I cannot say this for sure, but the claim that DSV is a "subsidy" slightly reminds me of claims like "BCH is fiat" or "Lightning is P2P while BCH isn't".
Things, that are somehow true, when you skew the definition.1/2
No clue about techincals behind this, but it sounds like someone telling me the sun is a "subsidy" and better to use candles instead. That of course has nothing to do with subsidies.
