I agree in general, but in this case it was pretty clear-cut: TrustCor was a CA primarily to serve a single product, MsgSafe.io. This is the same product that was found to have bundled the only known unobfuscated Measurement Systems malware and was also found to be claiming E2E encryption when very rudimentary tests showed they couldn't possibly be encrypting the email.
Since their only known benefit was issuing certificates in support of a quite-possibly-shady email system, I'm comfortable with saying that the cost-benefit analysis comes down firmly against TrustCor.
