In reply to Remy.

It's really strange when people claim to support mutually contradictory positions. If updating a plugin is all you meant, @Remy, then why call it a SaaS? You do know that SaaS means a hosted solution, don't you?

outside of WordPress, ... SaaS is hugely adopted and working fine.

For the providers, sure. But for users, it depends. What about providers who close? Or who raise prices significantly? Or who change their API, or their terms of business?

If you've never had that happen to you, congratulations! But don't generalize from that to think it's the solution. The recent changes to OneDrive's terms of business affected millions in just one go!
