Android Superuser situation - Busybox to Toybox, Licensing, insight & thoughts are welcome

Hi fellas,

I'm a pure android enthusiast, have been using rooted and custom ROM modded devices since Motorola Droid (Android Froyo) to ZenFone2 (2.3Ghz version) (Android Marshmallow) to date. Now that Marshmallow had introduced the Boot verification, Samsung ships with Knox, DM Verity - checksum verification of partitions S7 & S7E, locking the device. On a side note the 6p featuring e-fuse type boot flag from Droid X days..

And now this XDA article (root apps breaking on the N preview) posts about this Toybox from BSD licensing moving away from more sophisticated busybox (Would like to know about how the BSD licensing works that part is very confusing to me..I think the toybox's licensing is not like general more open GPLv2).

Could be wrong anywhere, please feel free to correct..

Now the doubts part,
Does this mean Google and all OEMs wants to lockdown the SU access once and for all ?
Is it even possible on Linux based OS which is Open source ?
What is the point of Fastboot unlock on Nexus phones if google wants this way, I know they want to inject those ads into our brains where ever possible but isn't this asking too much of leverage & crossing the line ?

Unfortunately I'm just a tinkerer not an expert programmer or developer to understand things a bit deeper, any valuable information and thoughts are welcome !!

Anyways just for the kicks,
Here's an archive (Src - XDA) on 0 google approach for using Android but this shadows the more robust cloud dependancy a double edge sword nonetheless..

Thanks for your time...

 

You're very likely greatly overthinking this. The general consensus (and that of a famous XDA developer that posted about this a while back) is that the 6P e-fuse does absolutely nothing whatsoever, does not void warranties, does not prevent rooting or installing custom ROMs, recoveries, etc. Nexus is literally a developers phone and very likely will remain so for a long time to come. Other phone companies may or may not want to lock down SU access (leaning more towards may), but Google doesn't seem to care too much either way. If you value rooting and custom ROMs above all else, Nexus is the way to go and likely always will be.
