Exactly. We don't see OA as the problem. OA solves many issues that exist with traditional publishing and also makes it easier to preserve content in the first place. The problem lies with decreasing library budgets, rising subscription prices, and that preservation services often are not suitable for smaller OA journals.
LOCKSS provides a free option for publishers to join, but only accepts a limited number of OA publishers (https://www.lockss.org/use-lockss/publishers). A couple years ago the PKP launched their preservation service, which we're really excited about as it also offers free preservation (for OJS journals) and would help esp. those smaller journals that otherwise couldn't afford to enroll into preservation schemes.
