[Magisk] pndwal:
You're either kidding or baiting me! ... so I'll oblige 😛 :

You want a closed-source wholly Chinese owned and controlled commercial root solution? Be my guest! (Jorrit has assured users that these people have their hearts in the right place after all!)

Some cut / paste info from an ancient XDA post:

@Chainfire (Jorrit Jongma) certainly paved the way (for Magisk / contemporary root). He has more time for photography and ten-pin-bowling now though. ;)

John Wu has had no such luxury. Even compulsory military service didn't slow his releases as much as many feared, and SU development has kept pace very well; the number of modules contributed by others also quickly became a tad overwhelming!

Soon after Magisk's debut, @Chainfire sold SuperSU to the Chinese company Coding Code Mobile Technology, CCMT, and contracted himself to them to help maintain it for a fixed time.

He may have known the writing was on the wall for SuperSU, but was able finally to make some money and then retire from this project altogether, and good on him too - he's now a legend the development community, though he's still active with other projects (eg he launched firmware.mobi, a website dedicated to hosting factory images for as many devices as possible for the convenience of users. Also he has an array of apps and still maintains some like LiveBoot - shows logcat and dmesg onscreen as a boot animation as they happen).

This has also allowed for a timely and fairly smooth transition to a new mainstream SU in @topjohnwu's Magisk, the success and versatility of which speaks for itself.

It's now known for:

1) Being fully open source - a very important consideration these days. SuperSU is not, and many are feeling uncomfortable with this, especially now @Chainfire is completely hands off, and development is wholely in the hands of the Chinese CCMT company. (Before he left however, @Chainfire assured users that these people have their hearts in the right place, and that he had been conducting full code reviews as development went along and approves of the changes. No way to check though. Just got to take his / their word on that... What does that remind me of? - oh yeah - KingRoot!... Sad, but he did deserve the money.)

2) Being a Systemless Module platform for devs to contribute value added functionality, some of which I've enumerated above.

3) Magisk Hide, which stays one step ahead of Googles Compatibility Test Suite, can pass SafetyNet check tests (hiding unlocked bootloader etc), hides root from apps, and allows banking apps, Google pay, Pokemon etc etc to work on our rooted devices.

4) It also has an advanced toolset, and can be tailored for many unique / unusual configurations.

Interestingly, @Chainfire supports his own apps (like Liveboot) using Magisk SU.

This SU Legend, XDA Moderator Emeritus & Senior Recognised Developer said just days ago (21/03/2019) ”are you using a proper root like SuperSU or Magisk, or are you using lineage/cm's bastard stepchild of a contraption?". Enough said?

Sorry I haven't bothered to answer your question directly. 😜

(I wrote this essay I never intended to write in an obscure Lenovo thread; thought I may as well stick the gist of it here.) PW
