Today's mania of "data", most of the time meaningless (they "prove" different and often opposite things depending on how you arrange them) it's a way to silence discussion or prove true false things.
Consider a simple thing: traditional FOSS model consists of:
- upstream devs that release their code
- many independent packagers of various distro check out that code and package it
- users get packaged code by their distro
This means that many eyes see the code at minimum enough to compile and figure out why it doesn't work properly in their distro. They often patch and suggest improvements. Users get different binaries on different distros. Due to actual package model proprietary software can't be easily distributed as first class citizen by the vendor to the users simply because package an apps for any distro is unfeasible. Proprietary vendor have two options: allow redistribution so distro packagers (many different subjects) control distribution of their binaries or support only few distro leaving the over aside.
So in synthesis in this model proprietary software is not first class nor welcomed and many different subjects with many different idea, environments etc pass the code around make it more portable (or it's a pain to be ported), up to date (or it's a pain to compile on different distro since [br]deps aren't under upstream control and no unique binary is around to be tried to exploit thanks to various bugs.
In "container model" especially snap&c upstream package the final binary with all dependency. No more single independent distro packagers have to exists. No more need to be up to date for the upstream due to [br]deps updates on various distro. No more packagers check and improvement suggestions/patches from packager to the upstream. Only a straight line from "producer" to "consumers". Ideal situation for proprietary software since it can be now first class. Distro reduced to be a platform like a cargo ship instead of a compilation of various software, i.e. having different distros became meaningless since they are only a base for application.
That's is. On FOSS/traditional model collaboration of different subjects with different interests, idea, competence, scattered around the world is NEEDED by design. On container model no communication is need and there are "compartments" between "producer" and "consumers" instead of an heterogeneous blends between them.
Any time you reduce diversity, you compartmentalize, you empower people letting them operate "alone" you get bed results. That's the best "data" to back up such assertion. Is freedom and collaboration vs isolation in a rigid, compartmentalized system.
To have a big "security proof" take a look at how many vulnerabilities and how serious they are in proprietary products vs FOSS software.
