Kind of. However, I think the mentioned problems about SAAS are valid.
I feel like they attack from the wrong angle. Consider BareMetrics an SAAS. They aren't really just a CRUD, but are lumped in with CRM's. The easiest CRM is a spreadsheet and a mailer like SendMail.
But they have actually replaced many of the popular services with a crud and also mention that MailGun / Stripe are irreplaceable.
Many organizations have used Excel as a CRM and then hit a lot of problems. It is very hard to scale up and also hard to add features to if you need them.
