I thought a polite email to this mail would be considered nice. Also, I didn't blog or put anything on social media, did I?
If you consider the conversations happening on github and our developer mailing list 'flaming', well - sorry, but people speak their mind and they consider skipping the upgrade routines dangerous for user data - which it is. I see jabs at the ownCloud developers on this list too, and don't complain about that.

Let me try to put it in a different way.
On each mayor upgrade, ownCloud runs upgrade routines which migrate data in the database to a new schema. These routines only run from one major upgrade to the next and don't work when you skip a release.
Without these routines, data loss isn't a "maybe" but a guaranteed thing. So, this patch alone WILL be sure to lose user data.
As I noted, we've been working hard to make sure users don't lose their data, hence, we get a little upset when a downstream undermines these efforts.
Now, if you plan on making more changes, like, letting the upgrade routines of each intermediate release run upon upgrade or something like that - we have decided not to try and make that work due to the risk involved so you won't really be able to count on help from us, nor would we be OK with that unless you undertake, somehow, a very major testing effort akin to the work CERN did with Smashbox.
In other words - even if this is unfinished, we think it is too risky to try.

Fedora seems to be working that way , though of course running git master is not smart as the upgrade routines only work from one major release to the next, not on daily snapshots.
But, to answer the real question you're asking: the solution is to provide a new version more regularly. I wrote a blog about that . You want utmost stability, so I suggest to upgrade to the latest patch release of N some time after N+2 has been released as latest ownCloud release.
That would mean that the oldest version you ship to users on any Debian, right now, is the 8.1. Anything older is NOT more stable and provides nothing but a worse experience.

Fair enough, we're working on providing 'smarter' packages. Note that the reason we dumbed them down to a "tarball stuffed into a *.deb" was to avoid users losing data - I don't know what you put on your ownCloud but mine has enough important private documents that I prefer safe over easy to use.

Hence my email.
I still consider that a courtesy - we have a lot of platforms to support and while we could follow most other projects in just providing zip files or, indeed, follow the general trend to virtualization, I personally feel distributions can be beneficial to software deployment, even for web apps. Moreover, I still have hope that Debian can adjust its policy of shipping known insecure and outdated software .
