Probably. In some amount of fairness, Trustico's stated motivation was that they didn't feel like they trusted Symantec (reasonable!) and the same people were involved with the move to Digicert (which I think is correct, some employees moved but technical oversight should have moved to the more organizationally-competent Digicert team) and the same problems were likely to happen again (I think Digicert is generally good at being a competent CA, but it's not unreasonable for them to decide the risk is too high if some of the same people were around).

They also state in the MDSP thread, "We were also a victim whereby Symantec mis-issued SSL Certificates owned by us, subsequently we were asked to keep the matter quiet, under a confidentially notice."

The big Symantec problem was RAs rather than resellers. The difference probably doesn't mean much to customers, but it means a lot in terms of trust.

Symantec trusted the RAs to do Validation. So although we believe CrossCert (the Korean RA which made all this kick off) were actually making some sort of attempt to validate, since Symantec exercised no effective oversight and relied entirely upon third party auditors (whose role is _audit_ not actively overseeing everything) we can't be sure. We know CrossCert validated bogus certificates for example.com, which although it's scarcely google.com or a major bank is still very wrong. Executives at Symantec essentially did not do their job on this, that's why even if they hadn't quit the market voluntarily they were in the process of being forced to let somebody else do the actual oversight. Board-level incompetence is very widespread, but that's no reason we have to tolerate it in the Web PKI.

Trustico was not trusted to validate things, so if they tried to sell some customer certificates for example.com, the customer would have to prove to Symantec that they legitimately controlled example.com to get their certificate. They could still cause (as seen here) mayhem, but only for their own customers, so arguably caveat emptor.
