I think the key reason this was seen as not being terribly offensive was the fact that women are disproportionately more likely than men to be on the receiving end of tons of different negative consequences when dating, thus to a degree justifying them having more of a safe space where their comfort and safety is prioritized.
However I think a lot of people are also recognizing now that such an app has lots of downsides that come as a result of that kind of structure, like false allegations being given too much legitimacy, high amounts of sensitive data storage, negative interactions being blown out of proportion, etc. I also think that this is yet another signature case of “private market solution to systemic problem” that only kind of addresses the symptoms, but not the actual causes of these issues that are rooted more in our societal standards and expectations of the genders, upbringing, depictions in media, etc.
To be fair, the SEC has only really gone after cryptocurrencies other than Bitcoin, which is the only major blockchain that uses the energy-intensive Proof-of-Work. The things the SEC was trying to regulate, that it considered securities, are almost entirely running on Proof-of-Stake networks, which have negligible relative energy consumption.
This will almost certainly have a lot of other negative impacts, but I doubt it will have that much on the climate.
