Industry: Please give us more regulatory clarity
SEC: everything not BTC/ETH is a security, please register them (read: and we'll throw it into the trash because we don't like it)
Industry: but these are clearly not securities, please give us more clarity
SEC: everything not BTC/ETH is a security, please register them
Industry: that's not an answer, we would like to trade crypto
SEC: everything not BTC/ETH is a security, please register them
So the SEC is clear, it's just that the clear answer the SEC is giving is not up to the tastes of industry.
But the SEC is also constrained by politics in the sense of external pressure making them not want to crack down, and by internal politics of hard-to-win cases about proving Howey tests that take forever.
So we have the current situation where the SEC has been very clear that it doesn't like any of the crypto stuff, but the industry pushes the boundaries and sits in the legal grey area where the SEC says it's not kosher but courts may or may not agree. Hence sporadic enforcement actions where they think they have a good case, which then leads to complaining (please more clarity), with the same response (none of this is legal, just because we haven't filed enforcement actions doesn't mean it's kosher).
Edit: ETH is kinda borderline; there is semi-widespread consensus that BTC is not a security, and no such consensus for pretty much anything else.
Edit 2: I don't mean the conversation literally. As far as I know there is no official stance on BTC, but one gets the sense that trying to argue in court that BTC is a security is a losing proposition, whereas <insert governance token for newnotscamcoin> is much closer to a winning case.
