It's complicated. In theory, SOC2 forces you to do some important stuff, like define your threat model and say "I can mitigate against the threats and prove that my mitigations are in place". The problem is always that the companies that care don't need it but are burdened with it while the companies that don't care will just checkbox their way through it. It sort of enforces a very baseline security posture, in theory, but the major win of "We've thought our security through" is more of a choice - SOC2 can't actually force you to care.

A ton of these SOC2 vendors take all of the potential good parts of SOC2 out of the equation, building the threat models for you and then you just hook up your gsuite/ github and they check boxes for you or tell you to flip a policy here or there. Delve took this to the extreme by not even asking you to flip the checkboxes.

That said, it doesn't matter if it's legit. Everyone is SOC2, and part of being SOC2 is that the vendors whose products you purchase are SOC2, so it's not a choice - you have to be SOC2 if you want to sell (industry/ product specific, but at some point it'll be clear if it applies). If your goal is security, well, SOC2 is irrelevant.

Ultimately, you'll end up having a separate compliance team to manage SOC2 and you'll actively try to keep "real security" from it because real security has to change over time. You'll encode the absolute minimum possible into your compliance for that reason so that you can easily pass every year and then, if you care about security, you'll invest in that separately.
